Which way will you be headed after the game? I head back south and take the the back way on Artesia Road to 45 South. I've also stayed in Louisville a few times for late games and take the back way by the Horse Park to 25 West. I always park in the grass lot by Pace because it gives me easy and quick access to Octoc Road. It's $20 and just bring cash and pay. A buddy from Memohis heads back north after every game and he parks at a church off of Universiity (also $20). Another friend always stays in Columbus after the games - he parks by the Hump.
There are places to park all around, just pick a lot in the general direction from DWS that you'll be headed after the game. I also agree with another poster, park a ways out and walk. After the game, you'll be walking right past the guys stuck in traffic with high dollar parking passes. There was a game last year when I was almost to Meridian by the time a guy with a pass close to the stadium got off of campus and we left at the same time...
