Hi Allen,
Way back in about 1961-64 my Dad flew for Green Construction of Indiana. Bob Green ran a successful concrete company building highways in Ill, Ind, Ken, Tenn, and he owned the Executive Inn's at Owensboro and Vincennes. He also had the Howard 500 (looks like a Lockheed Ventura) that Dad flew for him registered in Owensboro, and they would periodically operate the airplane from that airport.
Cool.
Chris...
