Scott - where in Pennsylvania are you? If you're interested in face-to-face games, I know the folks with Circle of Swords in western PA run Shadowrun events. I believe there are also some people playing in the Lancaster area, and I'll be back to run games at Save Against Fear in Lancaster in the fall, schedule permitting.
If you're in reasonable distance of Bel Air, Maryland, I'll be running an adventure there for a local Gameday event on May 17th.
You can also check the Catalyst Demo Team website (
www.catalystdemos.com) and see if there are any scheduled events reasonably close to you.
