oh yeah, i forgot about the pa grand canyon. now's a great time to go, with all the leaves changing. they used to have plane rides over it when i was a kid, don't know if they still do that. if you decide on hershey, do it around halloween or christmas (avoid all the tourists) the park is open with a few rides around halloween. during christmas, they put up tons of lights and santa is there with his reindeer, even rudolf.
PA has it all. Enjoy the change of seasons. Especially the fall when the trees all change colors. We have many historic roads like Rt 1, the Lincoln Highway, and Rt 6 up in the north. Major cities with plenty of nightlife and entertainment. Places like the Poconos where you can go and just relax. Lived here all my life, I've been to plenty of other States and Overseas, wouldn't trade Pennsylvania for anywhere.
Tailgating for a Penn State home game in University Park/State College is a singular experience. For big games, State College becomes the third largest city in the state with all the people visiting.
Lots of breweries and there's also Amish country that people clamor over. Lots of history in PA from when our nation was very young. Gettysburg battlefield tours are impressive.
