Strange, here in Finland the upper bowls are always more crowded than the lower bowl cause the price is so much cheaper (50% pretty much).Yeah I think it was opponent more than anything. The problem is filling the upper bowl and it has been since our rebuild, though I would definitely know why anybody would not want to sit up there.
I always sit in the upper bowl (we only have 2, the lower and upper whereas you have 3 if I'm not mistaken) when I go with a friend or by myself. You see the ice so much better and it is much easier to read the game from up there.
Is the price difference not big enough to entice people to go up there? Maybe the Avs could try to sell some student/children tickets up in the upper bowl for a cheaper price to fill that one up as well?
