Agree with Dandy Don..post more?
My former instructor/shop owner in the NE gave me some excellent advice upon moving to FLorida: "Kathryn, diving Florida presents different challenges. It's 'real ocean' out there too, and don't assume because you are experienced in difficult conditions here that you will have learned everything you need to know to dive 'down there.' " He was right. The bottom line is this: each dive is different, presents its own set of challenges and opportunities to learn. I'm a by-the-book diver in that I always do the "buddy check" thing when diving with someone I don't know, and ask the relevant questions of my buddy/the DM/Boat Capt (currents, conditions, descent line or not, DM in the water or not, listen very closely to the briefing, take a compass heading on the line at descent, and always do a weight check no matter what. And when diving current, I take a couple of pounds of extra weight with me. If I don't need it, my buddy might (bouyancy is more challenging in two dimensions, so to speak, when one has to be vigilant in maintaining both vertical and horizontal positions in the water). This is a bit off topic, but your post reminded me that as Training Magazine says, "Good Divers Are Always Learning." Don't figure it makes much difference where the opportunity for it occurs, as long as it does.
