I live in South East Pa. The room owned by Bob Maidhof is Drexeline Billiards Club in Drexel Hill. Great room with history. Jimmy Caras played and Corey Deuel started there. As noted alot of history on the walls.
D&D Billiards in downington 15 years ago had huge talent for a small place.
Andy Toth (sp) and Joey Dipietro (sp) played there. When I was 17 and starting in action this is where you went to get tested. The room has moved since then and has very few players, but still hosts a yearly straight pool invitational with many recognizable faces.
I am pretty young as well so I don't have a large history knowledge.
Current:
The PA state tournament in Indiana is a must visit also. Great tournament with non-stop action this past year.
The Blaze and Joss tours also frequent PA often as well.
PM me if you need places to play or visit.
