That Linwood-Trainer-Marcus Hook area is pretty much just what you see on the show.But if they're that close to Philadelphia, it seems odd to me that they act like they are from a town in the middle of nowhere where the only thing people care about is a girls high school basketball team from the 90s.
I'm not familiar with the area, but it's hard to believe so little is going on in that world when they are actually in a major metropolitan area.
Its closer to Delaware state than Philadelphia.
