On Route 66, Narcissa, Oklahoma. From Wikipedia: The Narcissa D-X Gas Station, on 15050 S. Highway 69 in Ottawa County, Oklahoma, United States, near Miami, Oklahoma, was built in 1934. It was listed on the National Register of Historic Places in 2003. It was located on the last section of U.S. Route 66 in Oklahoma to be paved, in 1937. When listed it was "the main building in the once thriving village of Narcissa, located south of Miami in Ottawa County on Route 66." Edit: I was wrong. Further research indicates that this is not the D-X, that it has been torn down. This was an automotive repair garage and is across the street from the former D-X location.
