Unless they have changed things, you can enter the south side of the TAC from Alabama and park along Alabama. Our former AD was tying to limit that parking, so it may have changed since 2019 when I stopped coming over to tailgate after 20 plus years of tailgating.
You CAN NOT enter going toward hideaway park after 8:00AM unless you have a parking pass.
If you ignore HogDawg you'll be much less confused.
