From Richard Crabtree on Frisco Rails Across Missouri. We are still on the Frisco Highline Trail and our next stop in Polk County, Missouri is Graydon Springs, Missouri. We are at the Frisco depot at Graydon Springs, Missouri and on the Highline in 1910-1920s timeframe. Graydon Springs had a post office established in 1890, and remained in operation until 1940. The community has the name of Mr. Graydon, a Frisco railroad employee.
