That's like saying multiple fan bases take over Minneapolis and St Paul every time the Timberwolves and Wild each play at home on the same night. Honestly, Mpls and St Paul may as well be Fargo and Grand Forks. The fan bases don't typically intersect anywhere.
I do hope the WCHA succeeds, I really do. If the NCHC title game is Denver vs CC, you just might find me in St Paul instead, no matter who is playing.
