Not particularly strange, and not quite "on my commute", but this morning as I rolled past the dumpster on my way out of the complex, I saw a Rockhopper, sans wheels and brakes. I carried it back to the garage. It's a pretty small frame, too small for any of my kids, but I have a spare pair of 26" wheels and I think I can scrounge up some V-brakes, maybe I can make this suitable for somebody else's kid. I think my nephew needs a bike.
Also, about a month ago I snatched from that same dumpster a Dahon RV Mate III folding bike. The 3-speed IGH doesn't shift so good, but hey, the price is right!
