Best vis for me had been Blue Grotto near Williston, Florida, USA. Water was so clear you got the distinct impression that there was no water there. Other divers looked like they were hovering in mid-air. A narced diver (unlikely at BG's depths) might think they could remove their reg and mask and take a breath of fresh air.
