The Beavercreek Greene Town Center is in a distinctive-looking building with a community-town feel in The Greene - a pedestrian-friendly 72-acre development of top-class office accommodation and mixed-use space. The center is conveniently close to Interstate highway I-675. Dayton is one of only two major logistics central points in the USA, being within 500 miles of 60 per cent of the country's population and manufacturing capacity. It is the setting for significant industrial, aerospace and technological/engineering research and many of its innovations and inventions derive from Wright-Patterson Air Force Base. Associated with the birth of aviation, Dayton is home to the National Museum of the US Air Force. However, with the decline of heavy manufacturing, it has diversified into a service economy, including the insurance, legal, healthcare and government sectors.
