Summer and Fall on the U of M campus wouldn’t quite be the same without students and businessmen/women sitting with laptops in the park, reading, or sitting on a blanket with pets and friends. The Diag is friendly to all walks of life and careers, and for foot traffic or bicycles. Even on hot summer days you can always find the right amount of shade to open that book or sit and listen to a local musician strum their guitar by a tree.
