Bradley Anderson,
Interestingly enough, as we were exiting the 13th green, one of our group, a Floridian, commented on the red clay soil that was between # 13 green and # 14 tee.
As you ride from the Florida Turnpike, West on SR 60, you can almost see the curvature of the earth, it's so flat.
But, as you approach Lake Wales, you can see the terrain begin to rise.
I don't know the soil composition at Mountain Lake, but, I'd imagine there would have to be a good amount of clay to hold the water in those elevated ponds and lakes.
