Adding to the list of memorable town names. Who could forget......Virginville! Located just outside of Kutztown.
Seriously though. Philadelphia is a must see, if only for the history of our nation. Gettysburg is another must see. Standing on the field where Pickett lead his men during "Pickett's charge" and seeing the distance those men had to cover, while under fire, is humbling. If you're here for fun only. Check out Hershey Park and, to a lesser extent, Dorney Park. If you've been to Disney recently then these two places are gonna be a disappointment, but for local places they aren't too bad.
I've never seen Pittsburgh but for a ling time it was one of the largest steel producing areas in the world. Our state parks are beautiful and just driving through them will make forgot about all your troubles.
If you come to Philly just don't cross an bridges. While the we'll let you leave PA for nothing (because we know you'll be back) those nut jobs in Jersey charge you to leave their state (because they know how badly you want to get out!).
