Eat some Shoo-fly pie, some Lebanon bologna, funnel cakes and enjoy a sub sandwich somewhere. You'll also be close enough to Maryland to enjoy some crab.
Google gun shops and ranges, I'm sure you'll find some places to visit.
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” ― Samuel Adams
