I stopped in at a bike shop near my brother's in Falls Church last Sunday.

I've driven past it a few times and always seen a plethora of used bikes outside it, so figured I'd stop in and see what they had since I've been looking for some old/cheap parts for a commuter I'm building up. Very crowded, very fun bike shop - lots of parts old & new. I spent half an hour or so talking to the manager, they didn't have the size/type front derailleur I wanted - but I got lots of good advice and he showed up the bike he'd just built for himself.

Anyways, the manager said he'd gone to the Westminster bike swap last year and had gotten some great deals on some parts he'd been looking for, and that Velo Orange and a lot of places like that will be there with parts they want to clear out.

I unfortunately might be up in New Jersey this weekend, otherwise, I'd go looking for some parts I need.
