A few years ago when I first retired, i scrapped cars. Prices were up and you could make from 300 to 500 dollars a vehicle. If you were luck you could do 2 or 3 a week. Sold them at auto shred after i pulled the gas tank, battery Etc. It was hard work but fun. They pay in cash. It was always neat to walk away with 4 or 5 hundred dollars in cash. I called it "found money" I met many of the people you are talking about. I really want to write a book about them. I still see some of them around todays, Dragging shit to the scraps yard in their old illegal trucks. I would call the book "Scrap Heads" Really a hard working, very smart group of people.
