If you get up north in Michigan, try the Traverse Bay RV Resort
just north of Traverse City. The sites are beautiful, the location perfect. It is just off the main N-S highway (31) and in the immediate vacinity of Traverse Bay Resort with three great golf courses (including Jack Nicklaus' The Bear), and only a mile from Turtle Creek Casino. Of course there is the entire Traverse City and Lelenau Peninsula to explore. Forgot to mention, their rate was the same as any local KOA with much nicer surroundings and amenities.
