What it’s like
The place. Tyndall is a small city and the seat of Bon Homme County in southeastern South Dakota. Nearly all the homes here are lived in by their owners, and household incomes run below the county's. Few people work from home, and the typical trip to work is short. Winters are cold, with January the coldest month and a good deal of snow, while July brings warm summer days and a fair amount of rain across the year.
Work. Residents work mostly in schools, hospitals and social care, with shops, manufacturing and government close behind. Across Bon Homme County, the largest workplaces include the Bon Homme School District, a continuing care retirement community in Tyndall and St. Michaels Hospital, a critical access hospital. Unemployment in the county is low and unchanged from a year ago, though the county had somewhat fewer jobs last year than the year before.
Things to do. A short drive from town, Snatch Creek is a small river and the Springfield Recreation Area is a protected area good for time outdoors. A longer drive brings you to Lewis and Clark Lake, a large reservoir on the Missouri. The Niobrara River is another longer drive away.
