Lake Trafford. Look it up. Ski Oleski can be PRO - he knows nothing about sailing, but can beat off all the gators with his airboat operation. Florida Cracker if I ever met one, and a pretty stand up guy notwithstanding!

There are a ton of freshwater lakes in lake Placid, but is that considered "south Florida"?

If the person is thinking about SW FL, I'd be happy to assist, and PGP would probably be interested too.
