And if you do find a u-pull yard, expect to pay a cover charge to get in. Usually 5 bucks or so. Also, expect to be turned away if you’re not wearing at least minimally protective clothes. No open-toed shoes, etc.
You will also need to bring any tools you might need to remove the parts you’re looking for. And you will want to inspect them as well as you can before you pull them, because the guy grabbing parts from the car before you probably wasn’t too worried about damaging parts next to the one he wanted.
