I park in the research park and ride the shuttle there and back. Never had a problem and exiting is SUPER fast because you can easily hit the bypass out of the research park. The shuttles run pretty quickly typically. That being said, I didn't attend the Bama game so it may have been a cluster****.

ETA: Plus it seems there are always hot girls on the shuttle. It's always nice to have great views on the way to and fro. I'm still thinking of a pair of shorts from the UMass game...whew...
