Get some lemonade at Toomer's Drugstore. That's about it for things to do in "The Prettiest Little City on The Plains." You'll have all the normal chain places for chow. Check out if the Gator Club is going to be doing anything during the day since it is an evening game. There really isn't much to do around Auburn or Opelika.
Have fun at the game. I couldn't get tickets as I don't donate enough to Gator Boosters to get season tickets. I'll be at the UGA game earlier that day as a guest of one of their players who is a family friend of ours. I'm planning on wearing my Gator hat and doing the Gator Chomp when they "Call the Dawgs."
