Found a Specialized Shark for $5 at the Goodwill a couple weeks ago. Tubes were flat, but a inflated right up and hold air fine. Rear wheel is only slightly out of true; still perfectly fine for slow cruising. The shark's mouth is a bottle opener. My wife is damned happy with it.

Also found this weird little Bianchi for cheap at a pawn shop last week. It's a Sport SX "campione del mondo" -- so it's a mid- to late-80s bike (?) -- but it's got a bizarrely small front wheel. Unfortunately, the size of the tire has been worn off. The frame is for an extremely short person, as well. I might part the bike out, but it would be a real shame because it's just so neat.
