What it’s like
The place. Harmony is a small town in Rock County where nearly everyone owns the home they live in. Residents tend to be older than in most places, and household incomes run well above the county's, with few people living in poverty. Winters are cold and snowy, summers are pleasantly warm, and precipitation is spread fairly evenly through the year.
Work. Many residents work in schools, hospitals and social care, with others in manufacturing, restaurants and hotels, and the building trades. Among the larger workplaces in Harmony are Goex, which makes plastic film and sheet, and The State Group Industrial USA, which does low voltage electrical work. Most people drive some distance to their jobs, and only a small share work from home.
Things to do. Rotary Botanical Gardens, a botanical garden, is a short drive away, as is the Rock County Fairgrounds, a park. For time on the water, Geneva Lake is a longer drive away. Aztalan State Park, an archaeological site, is also a longer drive.
