Yeah, the Charlotte PaP is definitely a cess pool, but I have found a lot of stuff there that I really needed. It does seem to have gotten a lot worse over that last couple years though. Back when they first opened I used to go in there with half a wheel barrow full of tools, but the place is so stripped these days that really isn't necessary or productive anymore. These days I don't even bother with that yard unless I'm looking for something small and obscure, and when I do go there I try to travel light. Get in and out as fast as possible. I've never carried there, but I have definitely felt uncomfortable a few times.
For what it's worth, it's not that long a drive to the Porter Road junk yard down in Rock Hill, which is also a PaP type yard, and it's not nearly as stripped or a full of thugs.
