The U.P. can be very tempermental with its weather, particularly early and late in the season. Try to give yourself a window of opportunity for your trip. My wife and I had to leave Sylvania early and head for the protection of the Porkies a couple of years ago. A big ol' front with 60 MPH winds came in off Superior and we were camper bound for 3 days. That week was pretty much a washout. A fickle place, especially in the marginal months.
