Parking here during a game day is a royal pain the the butt. If you get here at about 12-1 you should be ok. Heck since its an evening game you may be ok if you show up at about 2, The game starts at 6:45 I think. You should have plenty time to tailgate and have a couple of beers.
Typically the best parking spots (near Sanford) are taken early by the real diehards or VIPs eg. President Adams buddies, notable boosters etc. If I had to guess your best bet as far as parking is concerned would be around the Ramsey center, the various parking decks scattered around campus or one of the larger dorm parking lots. Hope this helps and hope you have fun.
Go Dawgs!!!!
