Hey Rich,
I saw a listing of them online somewhere. I live north of you and there are none here.
I am a loner. Don't mean to be but that is just how I am. I like being around people but when it comes to doing things, I am just too spontaneous to be part of much of anything organized. I usually don't plan squat and when I do I usually end up not doing it. My normal hunt day starts when I wake up planning on going to work and then just call it off and head to the beach or to a park or other place on the spur of the moment.
If you go to google and check Treasure Hunting Clubs Florida, I think you will probably find the site that I did which listed several.
Good Luck,
DaChief!
