My dad works at a landfill where we live and often brings home bikes to fix up and give to neighbourhood kids or others that are looking for some free transportation. He has to sign a form that says he won't sell anything though as the gov't doesn't like people making $$$ off of their trash. Recently he picked up a few and is going to keep the 1st 2 for himself and my mom, the 3rd he is fixing up for my son when he is old enough, and the other I'm sure he'll fix up for some kid from the neighbourhood.
