Pros:
1) Not a course but a decent practice facility.
2) Obviously, lack of foot traffic make it easier to maneuver for your shots.
3) You can work on any distance shot from the short approach/putts, medium range shots and long distance shots.
4) When I practiced here, there was nobody around. Add in everyone else's reviews and the chances that you will have this area to yourself is pretty good. I would venture to say that percentage is in the high 80's.
Cons:
1) No teepads.
2) One sign, if that is still there, for all 3 holes.
3) Location has the area tucked away and can be hard to find so,
4) Just stick to Oak Grove Park and Micke Grove DGC's when in the area.
Other Thoughts:
After playing Oak Grove Park and being disappointed with Michael Faklis Park, decided to go here and just try and do some field work and let some rip. It took a while to find the spot and by that time, my friend and I were toast. We just practiced our putting and left for home. I guess if you had time to kill, it's worth the time to locate.
