I also parked on the golf course when I have gone to Michigan games. Tons of space to tailgate and park. Short walk to the stadium. The Michigan fans I encountered on my trips were always very nice. Even had fans shake my hand on the way out as they were leaving in the 4th quarter of the 2002 Hawkeye victory.
If you haven't already bought your tickets, make sure they are as low as possible. The upper rows seem like they are a mile away from the field. Hopefully, they have eliminated the obstructed view seats around the old pressbox after the remodel of the stadium.
