This is a great thread

I typically am a 1 ride per shorts girl, but have reused shorts where the ride I just did was relatively short. Like, if I ride 15 miles and don't get all sweaty then they're "safe" to me, though it grosses me out a little if I think about it too much. Don't ask me why, maybe I'm a little of a germaphobe. But after a longer ride, forget recycling them. I have also used the wash in the shower technique, typically on RAGBRAI where no washing machines are available and you have to pack somewhat light for the week.
