I lived in a small town and there was a guy who'd ride his bike everywhere, with big metal panniers usually filled with soda cans. He'd be out in all weather, with high-visibility gear on, and would travel all miles outside of town with hundreds of cans piled on his bike.

When I asked people about him, they said he had a learning disability and lived with his mom, and would sell the soda cans for a little spending cash. Everybody loved him, especially the town government who paid him a stipend to clean up the town and let him keep anything he found. Since I helped at the local farmer's market I met him quite a few times and he was always cheerful and friendly.
