JOHNSON COUNTY, Kan. -- When the news broke about Idaho Sen. Larry Craig and his arrest during an airport restroom gay-sex sting, police in Johnson County weren't surprised at all.

That's because Johnson County Park Police say they've arrested countless men caught having anonymous bathroom sex.

We sent our undercover producer to Antioch Park in Merriam to see what would happen.

It didn't take long.

In less than three hours, a man approached our producer and struck up a conversation that eventually turned to sex.

He asked, "What do you like to do?"

The man said he was a regular visitor to Antioch Park and admitted he was nervous about the possibility that our producer was an undercover police officer.

Sgt. Chris Pennington, with the Johnson County Park Police, wasn't surprised.

He's arrested teachers, psychologists, married men and single men over the years, he said.

The married men always ask whether he's going to tell their wives, he said.

Some of the illegal activity can be traced to a pornographic Web site, Pennington said.

Several years ago, someone posted Antioch Park as a hot spot for anonymous bathroom sex. After that, he said, the men started arriving.

Police stepped up patrols and crews removed the bathroom stall door but, park police said, it hasn't stopped the traffic.

Not only are officers constantly patrolling Antioch Park, but Shawnee Mission Park also attracts sexual activity, according to police.

It's so bad at the bathroom near shelter house No. 2, one Missouri man -- just trying to enjoy lunch -- recently filed a police report complaining that a man had walked up to his car and asked if he wanted to meet in the restroom.

He told police he’d been signaled two other times during the past two months for presumed sexual encounters while at Shawnee Mission Park.

And it's not only happening in park bathrooms.

In July, Overland Park police arrested two men -- total strangers -- for performing a sex act in the bathroom of the Oak Park Mall Dillard’s.

According to police, the men were caught in the act between the 18-inch gap below the stall divider.

Renowned sex expert Dr. Dennis Daley from the University of Kansas said while some men like the anonymity the stall divider provides, most of them simply feel they have no place else to go.

"What you're seeing -- men who might use restrooms, bathrooms, sex in parks -- it's the equivalent of teenagers in the backseat of automobiles, heterosexuals running off to hotels. The reason this gets the reaction is because it's about homosexuality,” Daley said.

Authorities insist they simply don't want a child walking in on something inappropriate in the park, or a shopper being solicited for unwanted sex.

KCTV5's undercover producer was not solicited at Shawnee Mission Park, but KCTV5 News witnessed a string of bizarre activities at Antioch Park.

KCTV5 News cameras caught several men driving in, circling the parking lot, walking into the bathroom and walking out. One man nodded at our producer, went inside, flushed five times and then walked out.

All were signs, police said, of men looking for sex.

One man pulled in, circled around and parked and then walked in and out of the bathroom three times. He then stopped and asked KCTV5's undercover producer whether he was gay or whether he was a cop.

KCTV5 News discovered the man was Robert T. Rowe.

According to court documents obtained by KCTV5, Rowe was arrested for having sex in Shawnee Mission Park in 1991. He was convicted and jailed for criminal sodomy and ordered out of public parks.

Rowe would not comment when KCTV5 News went to his house, and through his attorney, he declined to comment, but his lawyer pointed out there was nothing illegal about men trying to meet other men at the park.

Moms like Jennifer Kosmicki told KCTV5 News she just wished they'd take it somewhere else.

"It's kind of scary and kind of makes me feel uneasy," she said. "I bring my kids here."
