SCCA has a region here, it encompasses Tampa, Orlando, and Daytona, but I'm not sure where they autocross. Here in Tampa I prefer to Autocross with FAST, because they're far more relaxed as classing goes (with FAST I'm in Street Tire Modified < 3 liters, with SCCA I'm in effing Street Modified). I'm moving back to Daytona saturday, and my first autocross with SCCA will be sunday in Deland. As for track days, the main ones in the area are held at Sebring, Moroso, Road Atlanta, and Roebling Road just off the top of my head.
