Happy to help. So, on the map I showed above, as the circles get closer to the stadium, it gets harder to get a bunch of gear to the tailgate spot. The spot closest to the stadium is most difficult to access and I wouldn't recommend trying to set up there if you have a ton of gear. It is a great area though, and that is probably why that is where the pay-for-tailgate spots are set up.
The next closest circle is good, but only if you get a season parking pass in the lot between Bunger-Henry and Boggs.
Otherwise, the farthest one is the easiest and where I tailgate. I am including another map below. You can pull your car right up to the field and unload, then go park in the Student Rec Center parking deck (no season pass necessary). The bathrooms in the MRDC building are always open and sometimes also in the IC building. About a 15 min leisurely walk to the stadium. Lots of families out there and kids playing catch, grilling out, cornhole, etc. Real southern tailgating ; ) (Just don't take my spot! lol)
