It's a great atmosphere. The only part of the Saddledome that has annoying fans would probably be the cheapo $20 tickets that are sold from Safeways on gameday and are WAAAAAAY up in the nosebleeds. Those fans up there can be royal douchebags sometimes. But the vast majority of the fans are pretty awesome, like most cities I guess
Edit: About the playoffs. The worst thing that happened in Calgary during our big run in 04 was the "Shirts off for Kiprusoff" chants on the red mile. So if girls flashing their tits aren't really your cup of tea, you probably won't have a good time, lol.
