Hi David & Kathy,
There really aren't many members in Florida period, but by doing it in northern Florida, you have the chance to broaden your market by making it possible for those in the NC/SC, Georgia, Alabama, Mississippi, all be able to come. If you start getting too far down the peninsula, less people will want to come.
It's actually the same dilemma I had with the Michigan one, I couldn't go too far up into Michigan because fewer people could drive around all that way to come up, so that's why it's only about a 1/2 hour from the Ohio/Indiana border.
I don't really know of any active members from Florida anywhere south of Tampa, so going further down would make it difficult. Anyone down there would also be wintering like yourselves, and at this point we don't have too many members who do (or post that they do anyway).
If you happen to meet anyone with a Sunline when you get down there, make sure to let them know about the meet & greet!
Jon
