5 Roadside Attractions Worth a Stop

While Disney World and the beach are fine vacations for some, I still prefer the great American roadtrip with all its quirky, unplanned side stops along the way. Click below for an interactive map version of the article, or read on to find out more on these classic roadside stops.

1. House on the Rock

5754 Hwy 23, Spring Green, WI

The Wisconsin Dells area is full of tourist traps, with an unusually high number of water parks for an area with cold winters and enough cheese shops to satisfy an army of hungry mice. But an hour outside of the main part of the Dells in Spring Green, WI, is The House on the Rock, a monument to a disgruntled architect and the crazy collections held inside its walls.

After being told by Frank Lloyd Wright he wasn't fit to "design a cheese crate or a chicken coop," Alex Jordan, Sr., vowed to "put up a Japanese house on one of those pinnacle rocks" to show Wright what he thought of his opinion. His son, Alex, Jr., started construction in 1945; by 1961, the house had already become a must-see attraction in the Midwest.

Nowadays, the focus is not so much about the house as the contents held within it, and the rest of the additions that have been made to the house since it first opened. Starting in 1968, the house began to display the unusual collections of Jordan, which grew from one room in the house to the whole complex, which was sold to a family friend in 1988. The museum now contains massive collections of dolls, a giant carousel, a 200-ft. model of a whale, and the Infinity Room, a window-filled room which juts out 218 feet from the rock without supports, providing spectacular views of the Wisconsin countryside around it. The collection continues to grow, and the tour of the entire facility takes over 4 hours. [Earlier this year, Stacy Conradt paid the House on a Rock a visit. Check out her Armchair Field Trip.]

2. Wall Drug

510 Main St., Wall, SD
Wall Drug

Another long-standing Midwest tourist stop, Wall Drug is famous for the ubiquitous wooden signs advertising its free ice water and the many different attractions that have made it more than just an average shopping mall. Ted Hustead, a pharmacist from Nebraska, started Wall Drug as a drugstore, and the small store experienced low business until Ted's wife suggested advertising free ice water outside of town. After the first sign advertising the water was placed, visitors started increasing, and they've been busy ever since.

The crazy attractions didn't start, however, until Ted's son, Bill Hustead, took over the family business. Embarrassed since high school that all the ads were for a "small town store," Bill set out to make things interesting. Wall Drug now features a giant Apatosaurus visible from the highway, a fiberglass jackalope, a miniature Mount Rushmore, numerous animatronic creatures and bands, a pharmacy museum with a replica of the original Wall Drug, and numerous other attractions that have expanded Wall Drug from a small store to a complex spanning a couple city blocks that employs a third of the town of Wall, SD.

3. The Thing?

2631 N Johnson Rd, Dragoon, AZ
The Thing

This is what I think of when I picture a tourist trap--a place in the middle of nowhere, promising something you can't see anywhere else. 'The Thing?' has been showing visitors "The Mystery of the Desert" since 1950, and has remained in its current location just outside of X since 1965. The main building is your standard roadside "trading post" that sells jewelry and moccasins, but for a dollar's admission, you get to not only see The Thing?, but all that leads up to it. Three long, open-ended steel sheds are filled with a variety of odd displays and artifacts, and The Thing? awaits you at the third shed. It wouldn't be a tourist trap without a gift shop full of everything from Thing? t-shirts to Thing? bottled water. Whether The Thing? really contains a desert mystery or just a bunch of oddly-arranged junk is up to those to visit, but it still remains an interesting stop along the road.

4. Coral Castle

28655 S. Dixie Hwy, Homestead, FL
Coral Castle

An unusual monument to unrequited love, this "castle" of sorts also serves as a mystery of how it was created. Jilted by his bride at the altar, Ed Leedskalnin began to build something he thought would impress her. How an open-air compound with rock tables, chairs, and beds built over 20 years was supposed to woo her back to him is anyone's guess, but the mystery that remains to this day is this: how Ed was able to move the 2.2 million pounds of coral rock required when he was only around 100 pounds? Ed was as reclusive as he was creative, and reportedly worked only at night by lantern. He died in 1951, and since 1953, the castle has withstood hurricanes and other disasters.

5. Cadillac Ranch

I-40, Amarillo, TX, between exits 60 and 62
Cadillac Ranch

America seems to have no shortage of unusual stonehenge replicas, made of everything from limestone to refrigerators (perhaps that's another article--anyone interested in learning more?), but the Cadillac Ranch in Texas is a monument of a different sort. Ten Cadillacs are buried nose-first, facing in the direction of the Great Pyramid of Giza. The cars were installed as an art installation in 1974, and remained there until the growth of the nearby city forced the installation to move two miles down the road to its current location. The cars showcase the evolution of the Cadillac's design, with both the birth and the death of the car's signature tail fin represented in the lineup. As the original color of the cars have faded, graffiti has been added, and even encouraged by the original group.

The cars also have inspired various movies and songs. The Pixar film Cars featured rock formations shaped like the standing cars, and the film's main setting, Radiator Springs, was set just outside of an area marked "Cadillac Range" on the map. Bruce Springsteen wrote a song titled "Cadillac Ranch" on his 1980 album The River. Clearly these cars are more than creatively-arranged junkers.

10 Monster Facts About Pacific Rim

Legendary Pictures took a gamble on Pacific Rim, Guillermo del Toro’s 2013 monster/robot slugfest. Since it wasn’t based on a preexisting franchise, it lacked a built-in fanbase. That can be a serious drawback in our current age of blockbuster remakes and reboots. The movie underperformed domestically; in America, it grossed just over $100 million against its $180 million budget. Yet Pacific Rim was a huge hit overseas and acquired enough fans to earn itself a sequel, Pacific Rim Uprising, which arrives in theaters this week. Here are 10 things you might not have known about the movie that started it all.

One foggy day in 2007, Beacham—who’d recently moved to California—was walking along Santa Monica Beach. As he looked out at the Ferris wheel on the city’s eponymous pier, he pictured a looming sea monster. Then he imagined an equally large robot gearing up to fight the beast. “They just sort of materialized out of the fog, these vast godlike things,” Beacham said. He decided to pursue the concept further after coming up with the idea of human co-pilots who’d need to operate their robot as a team, which added a new thematic dimension.

“I didn’t know I had something I wanted to write until I realized these robots are driven by two pilots, and what happens when one of those people dies? What happens to the leftovers? Then it became a story about loss, moving on after loss, and dealing with survivor’s guilt," Beacham said. "That made the monsters scarier because now you care about the people who are in these robots.”


Pacific Rim was picked up by Legendary Pictures and handed over to director Guillermo del Toro. A huge fan of monster cinema, del Toro enthusiastically co-wrote the final screenplay with Beacham. Sixteen concept artists were hired to sketch original robot and creature designs for the film. “We would get together every day like kids and draw all day,” del Toro told the New York Daily News. “We designed about a hundred Kaijus and about a hundred Jaegers and every week we would do an American Idol and we would vote [some of] them out.”


In “Charlie Kelly: King of the Rats,” the tenth episode of It's Always Sunny in Philadelphia's sixth season, Charlie Day’s character gives us a darkly comedic monologue about rodent extermination. Little did the actor know that the performance would open a big opportunity for him. Impressed by the rat speech, del Toro offered Day the part of Dr. Newton Geizler, Pacific Rim’s socially-inept kaiju expert. “He said to himself, ‘That’s my guy. That guy should be in my next movie because if he killed rats, he can kill the monster,’” Day recalled during an appearance on Late Night with Jimmy Fallon. On the movie set, del Toro often joked about how much he enjoys It’s Always Sunny. As a way of repaying his director, Day helped get del Toro a minor role in the series.


Most of the film’s special effects were computer-generated, but not everything was digital. For the robot cockpit scenes, del Toro had his team build the interior of a full-scale Jaeger head. The finished product stood four stories tall and weighed 20 tons. And like a Tilt-A-Whirl from hell, it was designed to rock around violently on its platform via a network of hydraulics. Once inside, the actors were forced to don 40-pound suits of armor. Then the crew strapped their feet into an apparatus that Charlie Hunnam has compared to a high-resistance elliptical machine.

Certain shots also required del Toro to dump gallons of water all over his exhausted, physically-strained stars. So yeah, the experience wasn’t much fun. “We saw every one of the actors break down on that set except for the female lead actress Rinko Kikuchi," del Toro said. "She’s the only actor that didn’t snap."


Del Toro wanted Gipsy Danger, his ‘bot, to have the self-confident air of a wild west gunslinger. To that end, he and concept artist Oscar Chichoni developed a swaggering gait that was based on John Wayne’s signature hip movements. The Jaeger’s Art Deco-like design was influenced by the Chrysler and Empire State Buildings.


Hailed as the “fortieth greatest guitarist of all time” by Rolling Stone, Rage Against the Machine's Tom Morello rocked the MTV generation with hits like “Bulls on Parade” and “Killing in the Name.” Pacific Rim bears his mark as well. The film’s lead composer was Ramin Djawadi, whose other works include the Game of Thrones theme. Wanting to add a “rock element” to the Pacific Rim soundtrack, he and del Toro reached out to Morello. The guitarist didn’t need much persuading.

“When they asked me to put some giant robot riffs and screaming underwater monster licks on the film score, I was all in,” Morello said. Djwadi was pleased with the rocker's contributions to the project. As he told the press: “Tom’s unique style and sounds really defined our robots.”


A definite highlight of this movie is Gipsy Danger’s duel with the winged kaiju Otachi in downtown Hong Kong. Both characters were computer-generated, as were the majority of the streets, cars, and towers in this epic sequence. However, there is one moment which was at least partly realized with practical effects. Gipsy punches through the wall of an office building early in the fight. We see her fist rip through a series of cubicles and gradually decelerate until it lightly taps a chair with just enough force to set off a Newton’s Cradle desktop toy. For that shot, effects artists at 32Ten Studios constructed a miniature office building interior featuring 1/4-scale desks, cubicles, and padded chairs. The level of detail here was amazing: 32Ten’s staff adorned each individual workspace with lamps, computers, wastebaskets, and teeny, tiny Post-it notes.


Rinko Kikuchi in 'Pacific Rim' (2013)

Audiences reacted strongly to Kikuchi’s character Mako Mori, who inspired an alternative to the famous Bechdel test. Some critics praised the culmination of her relationship with Raleigh Beckett (Hunnam). Although it’s common practice for the male and female leads in an action flick to end their movie with a smooch, Mori and Beckett share a platonic hug as Pacific Rim draws to a close. Del Toro revealed that he shot three different versions of that final scene. “We did one version where they kiss and it almost felt weird. They’re good friends, they’re pals, good colleagues,” del Toro said.


At the end of the credits, there’s a tribute that reads: “This film is dedicated to the memories of monster masters Ray Harryhausen and Ishiro Honda.” Harryhausen passed away on May 7, 2013—two months before Pacific Rim’s release. A great stop-motion animator, he breathed life into such creatures as the towering Rhedosaurus in 1953’s The Beast From 20,000 Fathoms.

Ishiro Honda was another giant of the kaiju genre, having directed Rodan, War of the Gargantuas, and numerous Godzilla films. Del Toro has great respect for both men. When Harryhausen died, the director said, “I lost a member of my family today, a man who was as present in my childhood as any of my relatives.” He also adores the Japanese monster classics and says he’d love to see a Pacific Rim-Godzilla crossover someday. Maybe it’ll happen.


If you’re not familiar with the practice of “Sweding,” let us fill you in: The 2008 comedy Be Kind, Rewind is about two co-workers at a VHS rental store who accidentally erase every tape in stock. Hoping to save their skins, they create ultra low-budget remakes of all the films they’ve destroyed using cardboard sets and cheap costumes. It’s a process these guys call “Sweding” as a ploy to convince everyone that their (unintentionally hilarious) knockoffs were produced in Sweden. Since Be Kind, Rewind was released, Sweding has become a legitimate art form.

When Pacific Rim’s first trailer debuted in 2013, YouTubers Brian Harley and Brodie Mash created a shot-for-shot, Sweded duplicate of the preview. Instead of state-of-the-art CG effects, their version used toy helicopters, duct-tape monster masks, and an ocean of packing peanuts—and del Toro loved it. At WonderCon 2013, he praised the video, saying that it inspired the editing used in Pacific Rim’s third trailer. Harley and Mash happened to be at the same gathering. When del Toro met the comedic duo, he exclaimed “I loved it! My daughters loved it, we watched it a bunch of times!” Then he invited the Sweding duo to attend Pacific Rim’s premiere in Hollywood.

The DEA Crackdown on Thomas Jefferson's Poppy Plants

The bloom has come off Papaver somniferum in recent years, as the innocuous-looking plant has come under new scrutiny for its role as a building block in many pain-blunting opiates—and, by association, the opioid epidemic. That this 3-foot-tall plant harbors a pod that can be crushed and mixed with water to produce a euphoric high has resulted in a stigma regarding its growth. Not even gardens honoring our nation's Founding Fathers are exempt, which is how the estate of Thomas Jefferson once found itself in a bizarre dialogue with the Drug Enforcement Administration (DEA) over its poppy plants and whether the gift shop clerks were becoming inadvertent drug dealers.

Jefferson, the nation's third president, was an avowed horticulturist. He spent years tending to vegetable and flower gardens, recording the fates of more than 300 varieties of 90 different plants in meticulous detail. At Monticello, his Charlottesville, Virginia plantation, Jefferson devoted much of his free time to his sprawling soil. Among the vast selection of plants were several poppies, including the much-maligned Papaver somniferum.

"He was growing them for ornamental purposes,” Peggy Cornett, Monticello’s historic gardener and curator of plants, tells Mental Floss. “It was very common in early American gardens, early Colonial gardens. Poppies are annuals and come up easily.”

Following Jefferson’s death in 1826, the flower garden at Monticello was largely abandoned, and his estate was sold off to help repay the debts he had left behind. Around 115 years later, the Garden Club of Virginia began to restore the plot with the help of Jefferson’s own sketches of his flower borders and some highly resilient bulbs.

In 1987, Monticello’s caretakers opened the Thomas Jefferson Center for Historic Plants, complete with a greenhouse, garden, and retail store. The aim was to educate period-accurate gardeners and sell rare seeds to help populate their efforts. Papaver somniferum was among the offerings.

This didn’t appear to be of concern to anyone until 1991, when local reporters began to obsess over narcotics tips following a drug bust at the University of Virginia. Suddenly, the Center for Historic Plants was fielding queries about the “opium poppies” in residence at Monticello.

The Center had never tried to hide it. “We had labels on all the plants,” says Cornett, who has worked at Monticello since 1983 and remembers the ensuing political scuffle. “We didn’t grow them at the Center. We just collected and sold the seeds that came from Monticello.”

At the time, the legality of growing the poppy was frustratingly vague for the Center’s governing board, who tried repeatedly to get clarification on whether they were breaking the law. A representative for the U.S. Department of Agriculture saw no issue with it, but couldn’t cite a specific law exempting the Center. The Office of the Attorney General in Virginia had no answer. It seemed as though no authority wanted to commit to a decision.

Eventually, the board called the DEA and insisted on instructions. Despite the ubiquity of the seeds—they can spring up anywhere, anytime—the DEA felt the Jefferson estate was playing with fire. Though they were not a clandestine opium den, they elected to take action in June of 1991.

“We pulled up the plants," Cornett says. “And we stopped selling the seeds, too.”

Today, Papaver somniferum is no longer in residence at Monticello, and its legal status is still murky at best. (While seeds can be sold and planting them should not typically land gardeners in trouble, opium poppy is a Schedule II drug and growing it is actually illegal—whether or not it's for the express purpose of making heroin or other drugs.) The Center does grow other plants in the Papaver genus, all of which have varying and usually low levels of opium.

As for Jefferson himself: While he may not have crushed his poppies personally, he did benefit from the plant’s medicinal effects. His personal physician, Robley Dunglison, prescribed laudanum, a tincture of opium, for recurring gastric issues. Jefferson took it until the day prior to his death, when he rejected another dose and told Dunglison, “No, doctor, nothing more.”
