Ron, If you have time on the way north from the shoot, a day trip to Mackinaw Island is worth the time if you are interested in the early history of the US/Canada. Lake Superior Provincial Park, about two hours north of Sualt St. Marie, is a beautiful place with excellent camping on the lake.
As mentioned earlier, the shoot is a bargain. Your whole family can shoot as much as they want for $40. Last time I took the family to Compton it was over $120 for the family to shoot one day - my wife refuses to let us go back at that price even though it is less than a hour from home.
By the way, I can't make the shoot this year but expect to go next year.
