Back in June of 1967, I was working as a photographer for the Kingsport Times-News. I got dispatched to this service station, then known as Smith Shell, to photograph the aftermath of an accident: a lady driving away from getting gas snagged the hose of one of the pumps. The pump overturned, electrical connections were severed and a fire ensued, quickly extinguished by the Kingsport Fire Department. By the time I got there, the fire was out and the KFD was mopping up.
I just looked up the photo I took. It’s at newspapers.com.
The station was built in 1955 by J.D. Smith. I remember him well, but from the 1980s or so.
