If you're planning on giving the full moon to an Amtrak train on Saturday, police want you to know no funny business will be tolerated.
Last year, the jovial drawer-dropping party was shut down.
"Things have gotten out of hand to the point of open sex acts and total nudity. Last year was the first time we shut it down. There was a medical aid call and we couldn't get help in a timely manner," said Jim Amormino of the Orange County Sheriff's Department.
In 2008, the event drew 8,000 mooners along a stretch of tracks in Laguna Niguel, Calif.
This year, new but temporary parking restrictions are in effect along Camino Capistrano that expire on Sunday afternoon. But you probably shouldn't be driving to the event anyway.
"The vehicle congestion is terrible. Again, avoid bringing a motor vehicle to the mooning area as there are limited places for parking," according to moonamtrak.com.
And don't think of carrying alcohol outside nearby Mugs Away Saloon, said city representative Meg Waters, where legend has it the tradition began in 1979 when customer K.T. Smith offered to buy a drink for anyone who would run outside and "moon" the next train.
Since then, on the second Saturday of each July, people have lowered their inhibitions and pressed their naked buns up against a chain link fence as the trains chug by.
Mugs Away, at 27324 Camino Capistrano, holds only 49 people, Waters said.
"If it's full, you can't stand outside and drink," Waters said. "If you leave Mugs Away with a beer in your hand you're going to be arrested. If you're standing outside with a drink, you're going to be arrested. And if you think mooning is fun sober, well, I can't imagine that."
"We're hoping for a nice peaceful day," Amormino said. "The ideal situation is no mooning at all. You may or may not be arrested for indecent exposure. It all depends."
"We'll see what happens and take it from there," Amormino said.
"Our main concern is public safety," Amormino said. "If it gets in front of our faces, the law's going to be enforced."
Thirty-nine Amtrak and Metrolink trains pass the spot between 7:30 a.m. and shortly before 11:30 p.m., Amormino said.
