Tunnel of Trees SxS Tournament and Game Fair - September 16 to 18th.
www.emmettunneloftrees.com Not a member but have shot there and know many of the members. Good folks and a Great Club. Am sure it will be a fun shoot. Nice aerial video of the course on the above link.
Michigan grouse season opens Sept 15th so a combination SxS Event and grouse hunt would be very doable. Over 80,000 acres of state owned land in Emmet County alone.
Also sounds like they will try to set up events for non shooting family members if there is enough interest. Things like boat trip to Mackinac Island, shopping trip to Petoskey and Charlevoix, or a boat trip on Little Traverse Bay.
