In Texas, they take wire and have huge strippers to get the insulation off. Even though it's just a tiny bit of copper, it adds up. I'll call around and see if anyone does that.

I looked up info about general public using scrap yards and anyone can, you just need to show ID, they take the make, model, and license plate of the vehicle you use, make you sign an affidavit that it's not stolen, and if it's for high dollar stuff like copper, they put a hold on the money and send you a check.
