What it’s like
The place. Robertsville is a town in Franklin County, Missouri. Winters are cold, with snow most years, and summers are hot. Rain falls fairly often across the year, so the seasons tend to be felt clearly. Many households are long-settled, and most homes are lived in by their owners across the county.
Work. Residents across Franklin County work mostly in schools, hospitals and social care, in manufacturing, in shops, and in the building trades. Fewer adults hold a four-year degree than hold one elsewhere in the country, and working from home is not common. Unemployment has eased over the past year, and the county has added a small number of jobs.
Things to do. Shaw Nature Reserve, a botanical garden, is a short drive away and suits a quiet walk among plants and trees. The Bourbeuse River, also a short drive off, is a good place for a slow afternoon by the water. Robertsville State Park, another short drive, offers a protected area for walking and being outdoors.
