Here is a listing of the different stadiums in which I have seen Michigan play football. Obviously the most common place I have seen the Blue play is at Michigan Stadium in Ann Arbor (around 90 or so games). After that, it has to be Spartan Stadium (around 10), then a tie with Notre Dame Stadium and the Rose Bowl (4 each).
The best is of course the Rose Bowl, but after that I would have to say Notre Dame and Ohio State. The worst is easily Ross-Ade at Purdue – it is like a high school stadium at the time. I know they made some changes to spruce it up, but it had a long way to go.
