I have a different perspective on the UND Hockey vs. NDSU Football debate. When NDSU was preparing for the national semifinal game on their home field last season, which many would argue was the biggest home game ever played in their history, I was able to pick up a couple great sideline tickets online. As I didn't have a huge desire to go to the game, I thought I'd see if I could make a few bucks off the tickets. The best offer I got was $80/ticket.
I know people who have gotten more than that for a regular season UND hockey game vs. Denver or Duluth. I also know people who have gotten $200/ticket for a regular season game vs. the Gophers.
