I am not a Pennsylvania native. I was living there because my husband was investigating a problem on the assemby line of one of the factories there. We lived there for less than a year. We did a lot of sight seeing during that time. Heck, we lived within 10 minutes of two National parks. Pennsylvania is just so beautiful to me because I love hills and trees. I now live in Indiana where there is not enough of either but it's still an OK place to live.
I went sightseeing in Philly once and at the end of the day, I realized I did not have enough money to get my car out of the parking garage! All the banks were closed and I was stranded with my 2 year old son. A museum employee saw me crying outside on a park bench and he gave me $10 and told me to get home safely. I have always thought a lot of PA for that reason too. People were friendly there.
I hope you get to take that trip this summer. the Pennsylvania Grand Canyon is up there too. Very nice.
