I was in Northern Michigan just a couple weeks ago, and tried hard to get my sisters to go on a little road trip with bikes up to Mackinac. The first few days it was 90o or higher - no takers. Then it cooled off, but brought winds gusting to 40kt. Still no takers. I haven't been there in about 20 years, and would really enjoy the opportunity to ride Mackinac. Maybe next year.
