For years I have been picking up metal off of the ground when I walk my dog -- aluminum and tin cams. The aluminum cans are almost always Bud Light and Pepsi which hoosiers through out of the pickup trucks.
I take the stuff to the recycling center every three months and get about $50, which fills up my van and also gets me a quart of oil.
Today, when I took my dog for a walk, I found three Bud Light bottle caps and a nusty nail, which goes into the steel/iron box.
Wire is the most profitable, since it's copper. I don't find much of that, but as for the Bud Light/Pepsi...the hicks must love that stuff. They throw the cans into the street, sidewalks, and people's front yards.
