I would join a South Florida club
i can't speak for any local clubs but Florida Trail Riders is a non-profit organization aimed specifically at our interests. not only do we get together regularly to race and have fun, as a group we are actively working in talahassee to get more land approved for LEGAL ATV/dirtbike use. there are currently about 2700 members with perhaps 10% turning out at each event. It is true that there are way more bikes than quads but who cares when at an FTR event 150 Quads turn up from all across the state to ride in a 40 mile - 2 hour race.
