I won't even wear my own dirty lycra.....but, I have a friend who did the AIDS Ride (seven days in a row riding) and he only had one pair of shorts. He'd wear them one day and the next day he would turn them inside out and wear them again. And then he'd reverse the process -- never washing them all week. His feeling was that by wearing the chamois outside, it was getting clean and disinfected in the sun and wind.

Oh, and he was 22 at the time. I guess young kids like CaliGirl's boyfriend (and my AIDS Ride buddy) have different standards than middle-aged women like us!
