I have enough trouble with people giving me cr*p for bringing a change of clothes if we are going out after a ride. If I wore a sarong with my group (think MIT nerds) I'd never hear the end of it. On Saturday we are going to a ride and party for AMC leaders after the ride. You can be sure DH and I will be the only ones who change. These people must have superior bodies, because mine does not tolerate sitting in sweaty shorts.
