Neither are Leo J Martin.... 
Just like there is only one Pine Valley, there is only one Leo J.
As a 12-year-old, at least twice a week, I would badger the pro shop guy into letting me play the back instead of the front when I only had time for nine holes after school (or on occasion just sneaking on). I'd usually play 12 as a short par 4 by hitting a tee ball across the river from the middle of the 11th fairway about 40 yards short of the green. 13 and 14 are already pretty good holes, and when you played 12 that way -- what a neat three hole stretch!
If I ever get back up there, I'll take some pictures, post an aerial, and start a thread asking for ideas about how to make the course significantly better without spending more than a few thousand dollars. I bet you could do it.
