haha...good for them being able to pick up a bike and take it out and immediately have some good results on it. Kinda like Mosher and Beenridin trading RM 250s and then Ben Rodgers proceeds to do well on the bike Mosher got on the trade...Ben had never ridden a drum brake bike much less ridden that particular drum brake bike!
I keep an eye peeled for a bike to pick up at vintage days but it's always a case of a bike being too nice/expensive or too haggard looking. Amazingly, a bike that REALLY caught my eye was a 1974ish CanAm 175 TNT enduro. Bike looked like new and was just cool looking! Stuff on it seemed really heavy duty looking, for example, the chain looked massive like maybe it was a 530? I asked the guy if he was selling it...nope. So now I have to look for a Maico and a CanAm.
