Welcome to South Fl, but.....coming from western NC, the off road riding may be somewhat anticlimatic. I just mean that we Floridians travel out to western NC whenever we can to experience off road riding that's more than just riding laps around a park and to get away from the hot, hot , hot.
Don't get me wrong, the trail riding quality is excellent and the SoFL riders are a great bunch of dedicated, enthusiastic people, but realistically, it's never a wilderness experience and extended climbs or downhills are non-existent. Don't mean to sound negative, but I just want you to know what to expect. Race scene is pretty good if you're into competition by the Gone Riding race promoters that you may have bumped into at Tsali.
Pretty active road riding scene, but we are ranked #1 or 2 in cycling related automobile deaths in the country. I better stop now...but welcome and I'm happy for your enthusiasm.
