Clarksville
Clarksville is a city in north Tennessee. The Customs House Museum, an ornate, Victorian building from 1898, offers local history and art exhibits, plus model trains. Northeast, surrounded by parkland, the vast Dunbar Cave complex dates back thousands of years and has many sinkholes. The McGregor Park Riverwalk follows the meandering Cumberland River. The river's history is traced at the As the River Flows Museum.
