The southern Californian city of Laguna Niguel has been enjoying an annual ritual, in which locals and visitors bare their bottoms at passing trains. For 30 years, the city has hosted “Mooning Amtrak” as crowds line up along the railway tracks, dropping their trousers when a train passes by. Up to 10,000 people take part, and visitors are encouraged to leave their cars at home and arrive by train. http://news.bbc.co.uk/2/hi/world/us_and_canada/10588850.stm added by: ampersand
