I have always scrapped aluminum cans because I live close to a forest preserve where there are a lot of company picnics. The area I live in has no city sponsored recycling program nor is there a deposit on aluminum cans like there are in some states.
I was just wondering if you could work out a deal with some management of the preserve where you supply a couple of plastic trash barrels (55gal) with your name on them and marked "alum. cans only".
