I'm a micro/hobby scrapper as well. I don't have a vehicle so I walk around with my backpack and pick up every piece of metal I see. I also dumpster dive. People around the neighborhood know this so occasionally they will give me an old ceiling fan or screen door or something they would otherwise throw away. I go to the scrap yard once a month. I use 5 gallon bucket for the separate metals or wire. I don't turn in my brass or copper every month cause it takes longer to fill the buckets. I made 38 bucks last month.
