If we are available that weekend, I'd go for a cruise to Frankenmuth - or there is also the Be-Cool car show on Water Street in downtown Bay City the weekend before that show.?.

Be Cool Car Show • Friday/Saturday, July 13 & 14
See the coolest in collector cars! On display will be a large number of antique, sports, muscle and custom automobiles and trucks. This is a cool event for a cool city!
