This was once Lucius Freeland's store. Foodstuffs were sold and after awhile gasoline pumps were installed; according to long-time resident Clarence Jones, "it became quite popular as a place to stop, buy, and visit."
In the 1940s, Mitch Lloyd took over the business, running it mostly as a filling station. After Lloyd, it was operated by Ira Ray (a.k.a. "Windy Bill").
The current building erected at the location was built by Owen S. Robertson circa 1960, and was operated as a gas station for some time before being used for other types of businesses.
It was the Riverside Restaurant & Catering in the early 2000s, operated by Dorothy ("Dot") and Leon Lea, and was wriiten about by Bob Garner for Our State Magazine in November 2007, and again in 2009. It is currently El Restaurante Ixtapa, which itself has been written about in the New York Times travel section (December 20, 2015).
