Sorry--I don' t have a schedule for MI (I am in MS), but the Three Rivers catalog will usually have the larger ones listed, Traditional Bowhunter Magazine has ads for them, and you might get some information from the Regional Forum here at huntingnet that covers MI. I am pretty sure there is a MI Bowhunters Orginazation that might come up on a search engine. I think the shoots are pretty much over for the year though, due to hunting season being open.

Sorry I' m not more help.
