There was a topless march here (Portland, ME) last year. Some controversy arose when men joined in. Details here:

I don't know HOW I missed that. Personally, though, I'd like it to go the other way. I don't want to see men walking around downtown without shirts on. It's classless. Wish they'd make it mandatory for all to wear shirts.
(NOTE: I spent 8 years frequenting the nude Black's Beach in La Jolla Ca. I'm not against nudity--just nudity where it's inappropriate.)
