If you asked me to pick a favorite, I would be hard-pressed. It would be easier if I could include the Atlantic Coast
but even if you moved me to Pompano, I would still make trips to all of these areas, as each has something unique. I will say that I've no desire to ever dive Vortex or Devil's Den again. Devil's Den was worth the trip once, but that's about it. Vortex was never worth the trip
