We took our summer trip early this year to WDW and sailing on the wonder. However it isn't summer with out a little get away. For us Mac Island is it. We love to ride bikes around the Island. Last year we rented, but this year we are taking ours. Sometime in Aug not sure yet. My friends parents have a cottage about 30 min from there so we will go up and visit them a few days and then everyone go to the Island for some biking.
When in Mac City be sure to eat at Scallywags. Wonderful fish and chicken.

Oh and the best fudge is Joanns. By far.

Funny that it is 6 hours from Chicago. It is 6 hours from Detroit.

From Detroit its pretty much a straight shot up I-75. Though my brother, sister, and I once took a really strange route up there. We left from where I live went up to Clare then Harrison then over to Cadillac then up to Petosky then up to Mackinaw. Talk about a screwed up way to go! It was fun though. We came home on I-75.
The dark fudge, and maple at Joann is to die for!
Still the non chocolate ones are good too. 2 years ago we stopped in Mac City and I couldn't have any fudge at all. DD was allerigic to milk and as a breast feeding mom, all her food went through me 1st. Man that is love let me tell you. 
Plus, traffic is usually pretty light at that time of day.
