What it’s like
The place. Sumner is a small township in Gratiot County, home to an older population than most places. Nearly everyone owns the home they live in, and renters are few. Household incomes run below the county's, and winters are cold and snowy, with a mild, comfortable stretch of warm weather in July.
Work. Residents work mostly in schools, hospitals and social care, with manufacturing, the building trades and retail also employing many. Across Gratiot County, the largest workplaces include MyMichigan Medical Center-Gratiot, Alma College and Gratiot-Isabella RESD Schools. Few adults hold a four-year degree, and a typical commute is fairly long.
Things to do. The River Styx and the Bad River are rivers a short drive away. Wright Opera House, a theatre, is also close by. For a longer outing, Maple River State Game Area is a park a longer drive away.
