Well I think the part where the article says it was a "fun family event" is NUTZ! I would never think of mooning as a family thing and certainly wouldn't want any children around to witness adults acting like morons in public.

Besides, aren't there indecent exposure laws? And what about the people on the train that have to see that?

I think if they want to shut it down, and raise money at the same time, ticket the crap out of every participant. Either the interest will dwindle or the city will make alot of money.
