I was just watching the replay of the Sounders vs DC United game here. Near the end of the game, the ESPN commenter points out that normally only the supporters at one end of the stadium stand for the entire game but that during this game the entire lower bowl remained standing (i.e. everyone except the people in private boxes). It looked and sounded fantastic. I have respect for what's going on in Seattle.
What pisses me off is that even if everyone in BMO wanted to stand for the entire game, thanks to MLSE and its Gestapo, it wouldn't be allowed. Damn it, at the last game a portion of our section was subjected to a "surprise ticket check" -- during the game! "Ignore the play. Get out your tickets now!" What a sin!
