Aside from concessions (I normally get what I want on the way to my seat...) there are so many things UL could do to enhance the gameday experience. Most have been covered here previously...
Utilize that damn bell! So many, many things could be done with the bell that would enhance the game and build tradition.
Pre-Game...The National Anthem. Bring in local talent to sing it. Think Sweet Cecilia. And sung acapela as well...the crowd singing at the championship game was awesome.
Would like to see a former player, coach, some person of note to the university lead the Ragin Cajun cheer before the team enters the stadium, sort of like the Who Dat cheer in NOLA.
Fly our championship and bowl win flags on gameday.
Turn the Cox Center into a museum of UL Sports History, open on Gameday (football and baseball) only. UNC and other schools have this, its really cool to relive these events and again, this is the sort of thing that builds interest and tradition.
