Pennsylvania is awesome but the United States is so varied, you can't go to Pittsburg and say; "I've seen America." Having said that, I will also admit that there are a lot worse places so, Pittsburg should do us proud. Where I grew up in coastal Georgia seems like a different planet from where I live now and I'm not just talking about geography.
Just know that things can often be a whole lot different out west.
