I was at my friend's place yesterday when she looked out the window and asked in wonderment "are those bicylists naked?" I couldn't answer her question because I was faced away from the window, so being a good friend I jumped up to see.
"Yup.................. They're naked alright."
I would guessimate there were between 10 to 15 bicylcist. I could only see them from behind. When we saw them they were riding down the street between a church and a grade school/park. They could be exposing themselves to charges of indecent exposure.
I don't know what point they were focusing on, but I've seen this type of behavior in previous years on the news. I can't remember why they were doing it, though.
UPDATE: Apparently riding naked is an event that occurs all over the world, according to my local news station. The reasons or purpose of it varies from place to place and year to year.
I didn't have my camera with me, but by the time I would have got it ready to snap a picture, the 'bikers' would have been gone. I'm thinking a cellphone camera would have been handy.
Perhaps the bicylcists were just helping to keep Portland weird. I'd say it showed their commitment, if that's the case. I sure hope they disinfect their bike seats afterwards.
