I am opportunistic. For the most part, I don't drive around looking for scrap. If I find something good, ill pick it up. I have directed other scrapers to piles I don't have the time or energy to pick up. I will also think to myself, "I'll leave that for someone who needs it more than I". Most of the scrap I get is stuff I buy at yard sales or get swapping out something I have a job working on. I will stop to pick non ferrous... Sinks and mag wheels. I will also pick up an AC whenever I see them.
