CL Rule 5: The bike isn't sold until the person shows up and hands me cash. I keep taking requests to see it.
CL Rule 6: Don't make plans around someone showing up to look at a bike. They come when I am normally going to be around for other reasons.
CL Rule 7: Corollary to Rule 5 & 6:, if they don't email an excuse within 8 hours of not showing up, goes to next on list.
