PHOENIX - Every year before the Super Bowl, Tammie Miller would gather her chinchilla coat and hop in a limo with her pimp. The host city, wherever it was, always offered a better supply of men than the lonesome highway in Long Beach, Calif., where she usually worked.

Miller was what’s known as a “circuit girl,” a traveling escort who, like any good entrepreneur, knows where the market is hot.

“We were in hotel lobbies, or out in front of the stadiums — wherever there were major amounts of people,” said the 37-year-old Miller, who quit the business two years ago.

This year, Arizona authorities have stepped up patrols, promising to sweep out circuit girls and their pimps before next Sunday’s Super Bowl.

But if the women are any good, Miller said, police won’t see them.

“They had no idea what I was doing,” she said.

Circuit girls are part of a clandestine sex trade that depends on their ability to blend with the wealthy. Unlike local street hookers, they’ll navigate the high-dollar crowd with ease, tapping men on the shoulder with little more than an innocent suggestion on their lips.

“I would walk up to them and ask them directions or some kind of help,” Miller said.

In Jacksonville, Fla., which hosted the Super Bowl in 2005, Roy Henderson, chief of narcotics in the Jacksonville sheriff’s department, said his officers arrested about a dozen circuit girls after staff at one of the city’s major hotels called to complain.

“I don’t know if you can spot them,” Henderson said. “A lot of times they’re very attractive. They dress well, where typically your street walker is in blue jeans, flannel shirt, rough looking. Those are the ones we’re picking up time and time again.”

Henderson said policing prostitution at the Super Bowl clearly is not as important as monitoring security threats, but several officers will be assigned nevertheless. And he warns his counterparts in cities about to host the big game to be on the lookout.

“A lot of girls are advertising on the Internet, and it’s a limited customer base that these girls had,” Henderson said. “But you want to protect the innocent folks who don’t want to be bothered by these individuals.”

The Phoenix area, which already is known among hookers as a lucrative stop in the winter because of the snowbirds, is expected to be irresistible to sex workers this year.

The Fiesta Bowl already brought thousands of football fans to the region at the beginning of January. And the Super Bowl was preceded by the Barrett Jackson car show and will be played on the final day of the FBR Open golf tournament, both major draws for wealthy, vacationing men.

“It’s a big deal this year,” said Tammy Marie Pagel, a 31-year-old local hooker who was recently jailed in Phoenix but was scheduled to be released the week before the Super Bowl.

Pagel said she had a number of high-paying clients waiting. She counted them on her fingers: one from Colorado, one from Massachusetts, one from Florida, one from Tennessee.

The johns saw her ad on the Craigslist Web site and set up appointments before setting foot in Arizona, Pagel said. Each will pay $500 to $600 for an hour with her — several times what she typically charges.

Authorities don’t know how many circuit girls typically descend on a Super Bowl city. But Phoenix police Sgt. Joel Trantor said officers will be ready for them.

“We’re going after the prostitutes, the people that pander to prostitutes — the pimps — as well as the johns,” Trantor said. “We’re going to combat this from every angle.”

Prostitutes who get caught face between 15 and 180 days in jail in Phoenix, depending on how many offenses they have on their record.

Miller said it didn’t occur to her to leave the circuit until police arrested her a few years ago.
