Shady Grove School, south of Lamar, Oklahoma
Approximately 4-5 miles south of Lamar and about one mile west.
Or what is left of Shady Grove School.  The Picture appears to be the still standing door and a rock frame around it.
Some rock walls can also be seen. The original Shady Grove was just to the west of the current one and was built of wood.
This is the one where my parents went to church on Sundays. That structure burned sometime later and the now rock one was built to replace it. - Sent in by Phil Kealthley
