There is an affluent neighborhood near here, that is a treasure trove on trash nights. Unfortunately you must be a resident or have a curbside recylcers' permit issued by the township. And yes, they watch for non residents.

When I discard bent rims or cut up frames, I have to wait until the the city recycling truck comes down the street. If I put them out the night before the battered truck monkeys will go thru ALL of my trash looking for more goodies.
