You know if you put a boat on the ice and do a backroll then you can also get the Boat Diver cert, just don't forget your mooring line so the boat doesn't drift away.
But man it looks cold, and to think I was a little envious, I mean right now I'm planning a 3 hour dive for tomorrow with possible humpback sightings in cold 75 degF water with 100+' of vis. I'll be wearing my hood and wishing for my drysuit. Time to go pack the scrubber.
