Hi Swampy and welcome to the site. I'm sure you can find somewhere / somone to ride with close to you. I believe that Rutledge ("fuller aviation" on the site) and "chrisivins" are both from florida. Also Dan Edwards is in Georgia. You may want to look in the local members section or the trail ride section to find some other AATVs near you to ride with.
In fact, here's a recent post by chrisivins looking for others to ride with:
Anyone in Florida?
If you can get together with another Amphibious ATV for a ride, it is much more enjoyable. Again, welcome to the amphibious atv forums!
