I beg to differ. I would argue that this may have been the case a while ago, and it's just my thoughts and not backed up by anything, but I think wayyyyy too many people walk around like their **** don't stink today. A chirp back from my buddy got us both a shot to the face, and although that's been the only altercation I've been involved in personally, I've seen a ton of them there, and it's all a result of some dude who loves talking but can't handle it when it comes back at him. Hell, nothing came of it, but I literally had a man who must have been 60 years old blackout drunk at the LRT station want to fight me because I had a Lucic jersey on haha.
That being said, this exists in every NHL arena I would imagine. But in the 10 years I have been going to the games at the dome, I just get that overall vibe from the fans there that "you're in our building, we can do whatever the **** we want".
I'm not scared to rock my jersey in there, it's just not worth the hassle. So instead I just don't go anymore. Surprisingly, the press level seats seem to be the least confrontational out of all the ones I've sat in.
When there is booze, there is fights. I've seen them in the arena, outside of the arena, at the Cowboys casino right by the dome. Maybe I've just had bad luck there. Because I've probably been to the same amount of games at Rexall/Rogers, and haven't seen a single fight. That being said, it would be a little skewed as the Flames/Oilers games would obviously be a little more heated, and that's not all I have seen in Edmonton.
