If you're a beer fan and near Harrisburg/Dauphin County, get to the Tröegs Brewery on a Saturday afternoon for a tour. It's a pretty neat operation to see, although they don't do any bottling on Saturdays. While you're there, pick up a growler of Rugged Trail for about $20 (around $8 for a refill.)
I just checked it out this past weekend (CC of course :D) and it was a pretty good (and cheap!) way to kill an afternoon.
