I'm headed to the Blind Pelican to watch the game today because I saw a U of M flag there last week. I will report back if I made a mistake and it's an off colored other team flag, but I think it's friendly!
Delayed edit: NOT a michigan bar. Didn't even play the Notre Dame game. Cooter Browns is still the best bet I've seen. Tough to find bars that will play Michigan while LSU is playing.
