My wife picks up beer cans. Rinse, redeemed at $0.05 each in this state, the money goes to the local animal shelters. About $100 worth each year. Most are retrieved when she runs. She use to limit her self to just 2 cans per run but now takes a plastic grocery bag or 2 to fill up. More money for the dogs that way. A couple times per year, she finds unopened cans.I find lots of beer cans.
