Well, today I bought a nice vintage road bike, with everything except wheels and brakes, from a local guy on Craigslist and went to pick it up on my commuter bike. I strapped it to my back with my belt, and stuck one arm through it to stabilize it, and rode home like that. About halfway home it started to rain pretty heavily.

So the commute today wasn't comfortable, but the end result was well worth it - a very nice vintage frame that I am going to repaint and possibly use as my primary bike.
