I posed this in a comment to their ratings:
I was very surprised that the Ralph Englestad Arena the home of University of North Dakota Hockey was not included. Even more surprise that Mariucci (Minnesota Gopher Hockey), Century Link in Omaha (Nebraska Omaha Hockey) and World Arena (Colorado College Hockey) were in your top 100. I have been to all of these arenas and they are very pedestrian. Mariucci has a corporate feel with almost no noise unless a goal is scored. Century Link is too large for Omaha hockey and portions are closed to make it more intimate. It doesn't really work. World Arena is a strangely shaped arena and not the best to watch a hockey game. REA reminds me more of the Excel Energy Center in St Paul where this are no bad seats, great atmosphere, and great hockey., I am guessing you were at REA when no students were there which obviously limits the experience.
PS. Great to see Amsoil Arena as your Number 1. Great facility and very intimate for a fan!
