Yes, Northern Lake MI this time of year is spectacular. The countryside, the shoreline, and the water is pristine.
Unfortunately, as you say, the launching options are few and far between, and it's sometimes hard to find the right wind directions for those few spots. I've kited up by the Mackinaw Bridge and Harbor Springs. I believe Cross Village used to be a popular windsurfing spot. At Harbor Springs you need to have access to the point, which is private property. We've done downwinders from there to spots along the North shore of Little Traverse Bay and to the state park.
But LZ's in between are hard to find, and often private land, docks, etc. On a strong West wind the swell can get really nice in the bay. Last year we played amongst the yachts that were racing in the annual Ugotta Regatta, boosting some nice airs across their sterns and over some of the entourage in tenders who were out spectating - lots of hooting and hollering!
I'm heading up there on our sailboat next weekend, from the 6th - 16th, to watch (and learn from) the International Moth North Americans, and hopefully get some tips on how to sail mine.

This is also my annual trip to do some sailing/kiting/exploring up North. Last year I did Franfort, the Manitous, Leland, Grand Traverse Bay. This time I may set sail from Harbor Springs to Beaver Island, and then on to Seule Choix Point on the South shore of the UP, depending on weather routing.
Seule Choix is a legendary wave spot, and a long way from nowhere. On a strong South wind the waves can be beautiful double overhead and peeling over the reef. Not too many options for protected anchoring, but I want to have a look anyway.
Otherwise I may hit Cathead Bay at the end of Lelanau Peninsula and Frankfort (by car), and end up in Suttons Bay or TC. If anyone is up that way and wants to go for a boat ride let me know.
As usual - the answer is blowin in the wind!
