I live in Erie as well, and concur. They are the pits. It wouldn't annoy me that much if most of the people my age (30s) wernt such bandwagoners. Growing up in the 90s I hardly knew any Steelers fans. I come back from the Marines in 2005 and the whole town is Steelers crazy.
On the flip side, its funny how Bills fans are now coming out of the woodwork in Erie. Wearing my bills stuff now I always get a, "go Bills!" like every single time. Before it was smart ass remarks like, "Oh, they still have a team?" I guess Erie is just a bandwagon kind of town.
