She wanted to place ads on Ashley Madison, a website where married heterosexuals go to cheat, but the site doesn’t take advertisers. In its first year, her business has proven tough to market. She began doing research - and promoting her business - at some of the area's sex clubs, from the Scarlet Ranch in Littleton, where everyday suburbanites cavort, to Mon Chalet on East Colfax Avenue in Aurora, a classic sex motel where couples and singles alike meet each other for a “walk on the wild side.” She hasn’t yet stopped by the Denver Swim Club or the Midtowne Spa, unsure of how she’d be received at the gay sex clubs - but she wants to find some way to reach gay men. So she started her own website to promote and operate Mile High Club Chalet, where she could advertise her rentals as erotic hotspots without any prudish oversight. She soon ran into trouble with Airbnb, though, which accused her of violating the terms of her agreement. In June she started offering up spaces on the Airbnb website. Grasmick had found a problem to fix: People having affairs needed places to meet besides overpriced hotels and their own, problematic homes. The short-term rental unit soon became an even shorter-term hookup unit. In early 2019, Grasmick explains, a friend who was having an affair needed a place to hook up, so the realtor opened up one of her Airbnb properties for daytime trysts. She has a lot of projects besides Mile High Club Chalet, a business she founded almost accidentally. She pledges to file paperwork with the bank by the end of the day. She helps a crying woman find a sanctuary for horses abandoned on her property. She makes sure one whiny tenant’s toilet is plunged. Her SUV swerves between lanes as she answers and solves whatever crisis has been called in. On a tour of her units in sleepy residential neighborhoods circling the metro area, she’s interrupted every few minutes by a ringtone from a popular meme, a cartoon duck singing in an old bluesman’s voice: “I’m about to whip somebody’s ass.”
What she is, Grasmick insists, is a fixer. “We’re not providing services, because that’s illegal and dangerous.” And Mile High Club Chalet, her string of two-hour-plus rentals for people looking to hook up, complies with the law. “It’s for people who want privacy and seclusion,” she explains. The 53-year-old property manager and real estate agent isn't a sex worker. Teresa Grasmick wishes that her friends would stop calling her the Mile High Madam.
