This thread got me thinking, "can people see my butt crack?" I just put my shorts in the washer, and before i did, I held them up to the light. Is there a difference between being threadbare and being able to see thro them a little bit? or is it just one and the same? Maybe that's why I've been "improving" on the group rides, I thought I was getting faster, but I must be passing the guys just cuz they're dropping back to check my shorts. Hahaha.
