re: First time ever at Tiger Stadium on 10/8. Recommendations on food/must-do's?

If you are on campus that early, go by the PMAC and check out Mike the Tiger's multi million $ habitat. Time it correctly and you can see the LSU Band march down victory hill. (North endzone side between stadium and PMAC) Its cool if you want the full experience, but again its an early game, so the hype will be somewhat lacking. They will release the times of interest later, but generally the band comes down 2.5 hours before kickoff, gates open 2 hours before kick. (DO NOT GO TO YOUR SEATS more than 15 min prior to kickoff) stay in the shade as long as you can. Pray for cloud coverage. The stadium is easily 20 degrees hotter that the air temp in that stadium if sun is blazing.
I would not go eat at a restaurant that early for breakfast, just wear some TN orange, be friendly, and bounce around campus tailgates acting like you've never had cajun food before and you will get your fill.
