Used to belong to the Iosco Sportsmen's Club - one range just east of East Tawas on US23, and another north of the Wurtsmith airport. The Tawas range has 25 and 100 yard covered lines; used to have trap but had to close it down when the adjacent beach club complained. The Wurtsmith range has 25, 50, 100, 200 and 600 yard ranges plus trap, sporting clays and skeet. Active club with great people.
The above was accurate about 5 years ago; I've since moved to Brighton and haven't had the opportunity to explore the options here. Part time snowbird also, so that limits my time here. I saw the above message about Howell, and I'm aware of Peacemaker's and Island Lake, and I think there's a Brighton Gun Club nearby somewhere.
