That's interesting. I thought I recognized the link. Rich is a real nice guy. I sold him the Peleton about 2 years ago that you see on there and the photos are from my Craig's list ad. He was driving a vintage car when he came to get the bike. Sweeeeet!!
I have not participated nor do I know if it still happens but he provided this link to me for those in SoCal and it has a few other links>
