I've been sending beat-up Ironman frames to a certain bike messenger in Montreal for a few years now.

Also, at Richmond's Bike Yard Sale, the messengers' sale table is by far the most fun to visit.
The parts are beat to heck, not worth a look, but the people are a hoot. Real folks, real cyclists.
They sell, chat, crack on each other, make enough for dinner and some brew, and make me glad they're around.
