On every second Saturday of July, people gather outside the Mugs Away Saloon, in Laguna Niguel, California, for the annual Mooning of the Amtrack.

Known also as the Mooning of the Train, this tradition dates back to 1979. Legend has it it all started when a rich person walked into the bar and promised free drinks to anyone with enough balls to show their naked behinds to the passing Amtrak train.

This year around 1,000 people attended the mooning and a great time doing so. there were no incidents, unlike last year, when many of the 8,000 mooners got intoxicated in public and the festivities had to be shut down.

The trains are mostly full when they pass by the Mugs Away Saloon and the conductors even slow down so the passengers can really enjoy the view.
