Webster (pop. ~1,700) is a friendly county-seat with a compact, walkable downtown and easy access to dozens of glacial lakes for fishing, boating and quiet outdoor time—an ideal low-stress base for multi-week contracts rather than feeling stranded in the middle of nowhere.
Highlights include the Museum of Wildlife, Science & Industry, nearby Waubay National Wildlife Refuge and community events that keep evenings and weekends interesting and restorative on longer stays.
For bigger-city options within roughly an hour, Watertown (~44 miles) and Aberdeen (~60 miles) provide expanded shopping, dining and healthcare for weekend escapes or supplies.
