I once sold a very high end tandem to a friend of mine. Before the UPS truck left the parking lot (it had an S&S frame) he called on the phone to ask how it looked. He had been tracking the shipment in real time from work.

Actually, I didn't get to see how it looked until I saw them ride the bike. I was afraid to take the bike out of the S&S shipping case for fear that I wouldn't remember how to get all of the parts back in.
