Last weekend was 'dump day' in my town. Officially, the policy is "No Picking", but as long as you don't get in the way, they usually don't care. The workers make their own piles of stuff they are keeping, and one man is also a 'bike guy', so he gets the best. Still, I snagged a Univega and a kids bike. They let me 'field strip' them, but wanted the basic frames thrown back onto the pile. I was OK with that and added to my collection of usable components.
