Depending on your version of tailgating, it ranges from really easy to really complicated.
The primary tailgating venue is the main quad in the center of campus. There’s a lot of structure around that, though. All of the good space, and most of the marginal space, is reserved for the entire season via payment to the University.
You can do that direct from the University, or through a few University-approved tailgate providers.
One that the University refers tailgaters to is Tailgate Guys. As with the Clutch! parking app, there is no connection whatsoever with TideFans. It is provided only FYI. Whatever you work out with them is between you and them, etc.
Cost varies with complexity of setup. It can be as simple as a tent and some chairs, all the way up to multiple tents, televisions, seating, tables, catering, bar staff, etc.
Cost also varies with the demand for the game. For example, the cost for a non-conference game against a directional school will be less than the exact same setup for LSU or Auburn.
As far as food and drink, if it’s legal, you can bring it on the quad. They also allow open barbecue setups, though I’ve always wondered about the safety issues of a zillion kids, all on sugar buzzes, riding Razers through there.
Even if you don’t go to all that trouble, it’s still fun to stroll through the area, especially on a big game day.
You can set up pretty much anywhere there’s space on University property. You might not have power, and a lot of people bring their own generators. Up to you to get the food, drink and equipment there and out.
Trash & Breakdown
The University is pretty good about having trash cans all over the place, and also deliver heavy-duty trash bags to tailgaters for free.
They’re strict about the cleanup, though. You have to be completely cleaned up and out by a designated time. Check with the University for specifics.
Especially on the east side of the quad, there are lots of food trucks, selling all kinds of stuff. Mainly dogs, burgers, barbecue, ice cream and the like.
My personal favorite of these is Jim’n’Nicks barbecue, but everybody has opinions.
