Penn plays in the MACHA (Division 2 ACHA) and Drexel is at the Division 1 ACHA (club hockey level).
The area is made up of club teams. Even Penn State does not have a D1 hockey team, they play in the ACHA Division 1 (and they have players who have been signed to ECHL contracts). So there is some competitive hockey in the area, just not at the NCAA D1 level. The only other NCAA hockey team in the area is Neumann College, and they are Division 3.
