First day wearing one of my new wicking tees from Lands End. Pretty cool morning, so it was hard to tell how much of a difference it made, but it was noticable. I suppose I'll get a better sense this afternoon when I ride home, temps to be in the 80s. Comfortably cool for DC in mid-summer, though, so I can't compain.
One of these months, I'll manage to get a cheap rack and panniers to keep the backpack off my back. Probably just in time for cooler weather when it won't matter so much. No, that's being overly optimistic. I'm thinking Christmas... :-/
