There are five sites in Dayton where one may follow the path of the Wright brothers to the invention of the airplane. Since John and I are already on the Wright Patterson Air Force Base, Monday we stopped at the Hoffman Prairie Flying Field located on base. Hoffman field in the late 1890s was flat open pasture land.. A Dayton banker, Torrence Huffman, allowed the Wright brothers to use that field for their flying experiments. His only requirement was that they keep his cows out of harm's way while flying their experiments.Trolleys from Dayton stopped at a small depot called Sims Station, located near the field. The depot allowed the Wright brothers to transport equipment from their bicycle shop in Dayton to the flying field. A replica of that depot is pictured below. No trolley tracks can be seen there today.
