Jeff,
Keystone park is only about an hour from me and it is pretty nice. Not too many side attraction except the drag strip nearby.
I used to camp a lot at Shawnee State Park in Somerset county. The lake is beautiful and you can drive to Bedford in about 20 minutes. You could see the historic Bedford Springs Hotel and Resort if you go there.....

Or you could see Old Bedford Village.....

Whatever you decide, let me know and I'd be happy to take a drive and meet you guys. It would also provide the opportunity to meet Drew Sagan. We've talked about meeting up for a couple of years now, but it hasn't happened yet.
