Though I'm an Iowan at heart, I've spent my 35 adult years in northern Indiana, which a lot of folks escape (appropriately, I might add) by going to the Traverse City area.
I made my first jaunt there a couple years ago, and it really is a beautiful area. Good bike/walking trails, some touristy stuff nearby. A little ways north is the "Tunnel of Trees," which truly is one of the most awesome drives one can take anywhere. My brother, an avid motorcyclist, would say the same.
