I drop into 69N once a year to visit my college roommate. Neat airport with the Lehigh water gap immediately north. There is a real gentle hike called "bake oven" about 7 miles west of the airport but you'll need a ride to get there. If you want something more serious, you should consider Tioga/Lycoming county area around the grand canyon of PA. Not sure if there are airports near by but its beautifully scenic out there, especially in the fall.
Wings in progress
