DandyDon:Hey that is so cool. I've done 47F, and it didn't hurt long - just until the capillaries in my face adjusted, as it was from a warm day. From a cooler day, but staying warm enough, it may not have hurt at all - just as long as it doesn't rob you of core temp.
I'm impressed with your attitude. It's usually the slender ladies who are more chilled and/or wimpy. You get great....! :cheering:
Hehe, you'll love Cozumel in the summer - just wearing a dive skin (body stocking).
Wimpy, no way! I pride myself in keeping up with and beating the "boys"! I can't wait to get into some warm water diving now!
