I didn't have the honor of going to Ann Arbor for my undergrad as I chose to go into the military for college. Where I went to school, Navy (yes, damn that pass attempt on the two point conversion vs OSU), tail gates are open to anyone and everyone.
What are the tailgates like at AA? Are strangers welcomed? I'm going to the game with my girl and we don't really know anybody but would like to make some friends at the tailgates. Anyone know of open tailgates, we are willing to pay for our drinks of course. It would be nice to talk football with fans instead of just heading to main street.
