A bit of a story first, source at the end. As the saying goes, it's who you know. My father is a metal scrapper as a hobby. Told everyone he wants junk, the family, neighbors and friends. It is amazing what he gets for phone calls, stop buys and what gets left in front of his garage door.
While we were talking the other day he was saying how the garage man got ahead of him the other day and took his treasure. Then remembered I have a cousin that drives a garbage truck and scarfs a treasure trove of items, truly amazing what he finds. Opportunity!!!
So, if you know a garbage man or have a network of friends and family that might, have them be "look outs" look out for lead for you. Those garbage trucks cover a lot of ground every week. We have found lead lying beside garbage cans on garbage pickup day and just wonder how much has been taken to the landfill. And by the way, this is free source. Would be interesting to hear how this works out for others.
