-If you like microbrews, you'll love Ann Arbor. The owner of
Ashley's is (or at least was in 2004) a Minnesota grad, and we were treated to a round of shots.
-Nice little downtown area with plenty of bars and restaurants. Try to take down Mount Nacheesmo at Tios, as seen on Man vs. Food.
-If you haven't already booked a hotel, do it soon - they sell out well in advance. We usually stay right by I-94, and it's an easy walk/drive to the stadium and cheap cabs to/from downtown.
-The golf course or Pioneer High School, which is across the street from the stadium, are the places to tailgate.
-You may be on the receiving end of some jabs from the traffic cops on the megaphones while crossing the street to enter the stadium if you're wearing Gopher gear.
-Michigan may have the oldest fan base in the Big Ten, other than Minnesota.
-The stadium itself...meh. It's a must-see just for the spectacle of being crammed in with 111,000 people, but the place just doesn't capture noise. TCF, with fewer than half the fans, can be louder. The recent renovations made the concourse much more pleasing to the eye, with lots of tributes to their rich tradition.
