I'm from the area, but I'm working this weekend. If I wasn't, I would've been happy to take you there. I'm sorry. 
However, you can rent a car and go from there. Carlisle is very close to Harrisburg.
Aww, thanks, it's ok! Yeha, I looked into renting car, but as I'm not 25, it comes with a hefty fine. I could always go cab, but I have a feeling that would run me 50+!
