You're about fifteen minutes from me man, and maybe 20 from Scott. Check out Susquehannock State Park, the view from the eyrie is worth the visit alone. Lots of trails around there. Small family campground, Muddy Run. Head over the 462 or 30 bridge, some neat spots along the Susquehanna. Check out PA's DNR site. A neat spot in York, Rocky Ridge, has some gorgeous views. Michaux state forest, between Gettysburg and Chambersburg. Codorus SP near Hanover. Rocks State Park and Susquehanna SP's right over the line in MD. Elk Neck SP in Cecil County. Literally dozens of small day/overnight hikes (although alot of the small municipal parks close at dusk) within an hours drive. Gander Mountain in York usually has a list of local get togethers and events. There are numerous sporting goods stores in the York area that will tell you little places to camp and fish.
Knife content for a bit, I was at Muddy Run's annual powwow, and traded for a well used custom made Hudson Bay chief camp knife. Brought it to Scotts campout last year, and found out from several members on here that it was made by Terry Baublitz. With a little TLC from Scott, I have been using it all winter.
BTW, Harpers Ferry is beautiful. I've got to get out there again.
