Sadly, many cities in the US do not allow picking stuff up at the dump. I had a discussion with our local recycle center, which is not a recycle center at all, it is a scrapping center. They regularly get bikes. But rather than reuse them for parts or even complete bikes, they say "no way". Instead they scrap them. As scrap, bicycles make lousy candidates as they are a mix of materials, from rubber, to aluminum, and steel. Yet they continue to not allow recycle, even to local bike co ops. Nope, its scrap all the way, every day.
