College football is a big deal at the University of Michigan, and you'll know when the Wolverines are playing by the crowds of avid fans pouring along the tree-lined streets to the stadium. The campus also has several excellent museums, as well as an arboretum and botanical gardens. Winters can be harsh — this is Michigan, after all — but even in the snow, Ann Arbor is easy to navigate on foot or bike. After a day of cheering on the quarterback or working up a sweat outdoors, spend some time relaxing in one of downtown's many bookshops before taking in a movie at the Michigan Theater and stopping in at one of Main Street's many eateries.
