I can imagine the warm water divers wondering why the heck we would bother diving up here in the cold, given the need for dry suits, thick gloves, hood, etc, plus all the extra weight (30 lbs is pretty light... I use 40, and my buddy uses 50) to sink it all. Fun climbing back up the hill at Sunrise Beach after a dive... I still laugh when I think back to my first dive in Hawaii... I picked up the weight belt (only 12 lbs!) and about threw it over the car!
The kicker is all the life up here. Very nice diving! I haven't been up as far as Port Hardy, but I'd sure like to! I think ol' Jacques Cousteau has been quoted as saying that one of his favorite areas to dive in the world was the Puget Sound.
My wife is a non diver... pity me....
