I attended MSU for eight months as a visiting student and I confirm that the old part of campus is quite nice. Frat house on saturday and sunday morning are also interesting with all the beer cups trashed all over the place. The Lansing River trail offer some pictures possibilities, especially if you go by bike. The city is also interesting where the river is crossing Grand River Ave. If you are into nature photography, the Sleepy Hollow State Park few minutes north of Lansing is a nice place to go for a quick outdoor after work. Regarding the Michigan Lake shore, I enjoyed the Sleeping Bear Dune park for a week-end out camping. The other mentioned place are also nice, like Holland for instance.
