Go here to see other courts. Look for 3928 Greencastle Rd, Burtonsville, MD (Fairland Regional Park). If you click on the "Rotate Camera Angle" "circle arrow" icon, for some reason, the pictures alternates between the old (all green) and new (blue on green) court surface.
Move your cursor until you see 6 small tennis courts.
They are below the yellow baseball diamond.
Then enlarge to the max.
Perhaps this picture was taken during a social.
Because you can see some people(dots) near the picnic table.
