Wow Zero,
Only have seen snow 3 times? When I first saw your avitar and photos on myspace, my impression of you was that you were made for snow. It must be the vast amount of facial hair, you know for protection from the snow.
Anyway, if you can take the cold so can I, so you have a dive buddy if you do ever get up there. I am sure we would need some seriously special equipment. I don't know any regulator that will be able to handle that type of cold.
I am thinking we will also need to put some type of heating system in our dry suits. Oh yea' some full face masks, I don't want my lips to freeze!
