I bought my Colnago from a friend/riding buddy who lives in a neighboring town. He was selling it for his brother; a retired Cat 2 racer from down in the San Fernando valley. It was his race bike, and looks it. Oddly, the frameset was originally sold to him at a shop that I occasionally buy mtb stuff from.
I received my Fuji in a trade with a guy who lives in Ventura. He has a pretty nice collection.
I bought my Schwinn from a nice Hispanic guy on CL
