Guys:
The whole FL things boils down to this -- when it's freakin cold people head to FL -- the issue when looked at the flip side is this -- when weather IS NOT the issue -- is there any real motivation to head to FL for edge-of-your-seat compelling golf of the highest order?
Look, I understand thoroughly, there are some people who could give a rats ass attention to anything that is architecturally compelling. They just want to play golf -- doesn't matter if there's a layout that is boring or flawed -- they are happy as clams doing it. By all means, I would tell these folks -- knock yourself out and enjoy what you are doing.
The simple reality is that FL likely has fewer zero courses than many other states I have been. Doak is quite correct there are hordes of layout that would be in the 2-3 range he outlined previously. No doubt you have a few higher up than that -- but even the best of the best from FL could not sniff the likes of a Ballyneal or Rock Creek or Kingsley Club or Black Mesa, etc, etc, etc.
