nope, can't do that. Could get a beater bike, though, or just clean your nice one well when you're done.
Well, you do have a star by your name. I'm sure it means something significant, as cicadashell has one, too. We'll just assume it's an asterix. You could put a little disclaimer in the space where people put pithy quotations. Something like, "*mostly" or "*fair weather" or "dry and warm". I won't hold it against you. You seem okay to me; I read your touring post.
I don't ride at night, and I'm sure that to some folks on this forum, that makes me a complete wuss. But I'm blind in one eye, and my depth perception ain't so good in the dark. I'm likely to ride straight into the Potomac river, thinking it's a bridge with all those lights reflecting off the surface. We all have our weaknesses.
