Yeah Vandergrift's the lawnchair place E... It was filmed a couple areas other than that though too. The park's down near my gf's place.
And you're right Bill, that was the guy. I remember it being on the news that girls from Hampton were camping out, so I guess that must've been filming at the same time in Hampton at their high school. I know I am #4 filmed at the Kiski High School (Vandergrift-ish) too. All right at the same time.
And now Batman...
Russel Crowe just filmed something here not long ago, I forget what it was off-hand (was it the movie about the guy getting his woman out of the Allegheny County Jail?), and he was riding his bike around Pittsburgh while he was here... I guess he got lost and asked for directions, and the guy he asked said, "You're Russel Crowe?", and he said yeah, and then the guy just gave him the direction he needed to go and walked back in his house... Russel said something about moving here because nobody bothers you and treats you the same... I thought it was pretty funny at the time. That movie looked interesting but I never saw it and I don't think it did well.
