That thing attached to the back of the bike is one of those wheeled magnets the roofers use to clean up nails after a job. I figure I'll tow this thing and it should catch all the parts as they vibrate off the bike. When I stop for fuel I can gather up the parts the magnet picked up, get out some tools and my bottle of loctite then start bolting stuff back on the bike.
Wrenching and riding. Schweeeet!
