I'm guessing by the lack of comments that there may be little to no interest in this event. I will be going. In 2015 I took my middle son Cooper. It was our first event in our mini. We had a blast and are looking forward to taking the whole family this year. That would be my wife, my oldest boy Ford, the middle boy and his dog Porsche, our youngest son Tucker, and our oldest dog Zoe. We are a car family - can you tell?
The last time we went there were about 7 classics 2 pick up, 1 of the more square front end minis, and the rest all classics 1 was even a v-tech. A bonus is that after the event you can take a waterfall tour of the UP. Maybe check Michigan's Superior coast line (Pictured Rocks, tahquamenon falls, white fish point, the wreck of the edmund fitzgerald, etc...) On the way back south you could hit the Lake Michigan coast line (Sleeping Bear Dunes, Grand Traverse County, Tunnel of Trees - this is a blast especially in the fall, breweries, wineries, good food, Petoskey, etc...)
