At 5:45 p.m. on a Tuesday, Maria Santos is hauling a pair of Bluetooth speakers through the side door of the Letts Community Center, a low brick building that also houses the town's food pantry and a single meeting room. By 6:15, seventeen women and two men have squeezed between the folding chairs and the veterans' memorial plaque. Santos, who has taught Zumba here since 2019, clips on her microphone and surveys the room.
"If you can walk," she calls out, spotting a nervous-looking woman in the back row, "you can Zumba."
The music starts—salsa, then reggaeton, then a Bollywood track someone requested on Facebook last week—and Letts City, population 348, starts to move.
Why a Town of 350 Needed a Dance-Fitness Class
Letts City sits in rural Louisa County, midway between Muscatine and Wapello, with no full-service gym and no stoplight. For years, residents who wanted organized fitness drove twenty-five minutes to Burlington or thirty to Iowa City. That changed after the pandemic, when Santos—a former hotel housekeeper who got her Zumba certification online during lockdown—started posting free outdoor classes in the elementary school parking lot.
"People were lonely," said Santos, 44, who lives in nearby Columbus Junction. "They wanted to move, but they also wanted to see each other. Zumba was the excuse."
The outdoor classes drew eight people, then fifteen, then twenty. By fall 2021, the Letts Community Center had invited her inside, charging just $3 per class to cover utilities. Today, Santos teaches four weekly sessions there. Two other certified instructors—her sister, Ana Santos-Ramirez, and Wapello resident Denise Holt—have added classes of their own, bringing the total to nine weekly Zumba offerings within a ten-mile radius of Letts City.
The Regulars: Who Shows Up, and Why
The Letts Zumba crowd defies easy categorization. On a typical Thursday, you will find Linda Meyers, 67, a retired corn-and-soybean farmer who started coming after knee surgery because her physical therapist recommended low-impact cardio. You'll find the Vargas sisters, ages fourteen and sixteen, who get dropped off by their mother after school. You'll find Brian Kowalski, 52, a line technician at a Muscatine power plant who drives twenty-two minutes because, he said, "the gym feels like punishment. This feels like a concert I'm allowed to be bad at."
Santos tracks attendance in a spiral notebook. Her oldest regular is 71; her youngest was eleven, brought by a grandmother. Roughly a third of participants come from Letts itself. The rest drive from Grandview, Morning Sun, or across the Louisa-Muscatine county line.
"I don't care if you go left when I go right," Santos-Ramirez told a first-timer during a recent Saturday morning class at the Grandview Community Center, a converted church basement with water stains on the ceiling and excellent acoustics. "I care that you're here."
One Night: The Valentine's Glow Party
If you want to understand how Zumba functions as infrastructure in this corner of rural Iowa, attend one of the themed fundraisers. On February 10, 2024, Santos and Holt co-hosted a "Valentine's Glow Party" at the Letts Community Center. Participants paid $10, wore neon, and danced under a single disco light Holt had bought secondhand in Davenport.
The event raised $340. Santos donated it to the Letts Public Library, which used the money to replace three aging laptops in its adult computer bank. Twenty-three people attended—standing room only—and two were first-timers who signed up for regular classes the following week.
"It wasn't a huge number," said Letts librarian Diane Foss. "But $340 is real money here. And they had fun doing it. That's the part that sticks."
Where the Classes Actually Happen
Geography shapes the experience. The Letts Community Center classes run Monday and Tuesday evenings in the multipurpose room, where participants must stack chairs beforehand and replace them afterward. Santos-Ramirez teaches Saturday mornings at Grandview's smaller basement space, which has no mirrors but excellent cell reception for streaming playlists. Holt added Thursday evening classes in 2023 at the Wapello YMCA, a fifteen-minute drive north, where a proper sound system and rubber flooring draw a younger, more athletic crowd.
There are compromises. In Letts, the air conditioning is a single window unit. In Grandview, the bathroom is up a narrow flight of stairs. No venue offers childcare, though participants have informally started bringing older kids to do homework in the hallway.
"The setting is not glamorous," said Holt, 38, who works days as a Medicaid eligibility specialist. "
