Do you want to rent a tent or are you going completely freelance ?
Where is your parking?
Beside and behind Barnes and Noble is easy to free lance and near the stadium obviously.
You can freelance and find a space at The Junction, easy, it's never full. But it requires a bit more work.
Tips. Stone and Bully Blvd is open to drive until 3 hours before kickoff. You can drive up to Barnes and Noble and drop off your gear and supplies and go park.
However after the game, you have to wait 2 hours after the end of the game for the roads to open up.
