I like the idea where the sitters switch seats with the standing fans, but then again I haven't had any real problems in Notre Dame stadium with this, and I'm 6'2". I try to be courteous, but you better believe I'm going to be on my feet when the defense is on the field, and occasionally the offense if it isn't going to disrupt them. I greatly dislike when the stadium has been hushed when they should playing the 12th man. Aside from maybe a game or two, '05 USC was the last time that stadium was really loud.
I don't have any problems with the ushers usually, most do a fine job. The usher in the boxed seats with us in section 10 has been there at least 8-10 years I would guess, always the same place, and he's awesome. I have had issues where fans that couldn't hold their liquor weren't removed. Most recently, the Utah game, there was some girl that was passed out 3/4 of the game, and she only woke up to vommit. She really needed to be escorted out, and people pointed out she was causing...hygienic issues...but nothing happened. This isn't always the case though, as I took an Army buddy to the Air Force game last year, he was sober and had a bad reaction to some food from earlier, and he was ejected for the game. I also received a nice letter from the University afterwards since I picked up his ticket. I had to laugh.
