Hi all. This forum is one I have been neglecting. Since I sold my 06 GT and got a new Boss I have been over the BMO forum for the most part. I too am in G'ville and go to Ocala, Tampa, and Jacksonville. Gainesville has an eclectic car group, Gainesville Street Rods. Even when I had the 06 it was generally the newest car there. Ocala has an MCA club as do Tampa and Jacksonville. A non-MCA club in Jacksonville, Modern Mustangs of Jacksonville (MMJAX) is a pretty good bunch.
I have not checked into the Daytona area, but Jacksonville has three mustang related groups and several other makes and some generic car clubs. Tampa and Orlando also have a number of car clubs. There are also Steeda and Brothers auto shops/retailers that host events a couple of times a year.
The big Mustang/Ford events in Florida are the All Ford show, in January, hosted by NPD and have been held at Silver Springs (this is up in the air right now). In April is the Mustangs and Mustangs - Legends having Fun, put on by the Imperial Mustangs of Polk County at Fantasy of Flight in Polk City. In the Spring and Fall there is a general car show hosted at Castro Farms - Ocala Pumpkin Run (Horsepower in Horse Country). There is a major Mustang event hosted by the Mustang Club of Tampa, but I don't have that info available right now.
There is a magazine, "Mike Kelly's Cruise News" that lists daily cruise-ins and weekend events. The magazines are generally free at the cruise-ins and available by subscription. He does host a web site, but it does not have event listing on the site. He does have a listings of car clubs so you can check that out. Click here
Hopefully this will get you started. Enjoy.
