More of a bragging right than really a bucket list, but living in North Carolina, I take a group of divers to New York (Chazy Lake and Lake Champlain) each year to do some ice diving. So the bucket list item (ice diving) has been filled. But to elaborate on that, I really want to go to the upper most part of the North Pole and the southernmost tip of the South Pole. Then I could brag and say I have dove on top of the world. I could even say I have dove under the world (although this doesn't make much sense, diving under the world, but you get the point). Further more, taking away the conventional scuba aspect, I still would love to sub it down to the bottom of the Mariana Trench (now that's deep diving, bet PADI doesn't have a specialty certification for that).
