Interesting. I honestly feel kind of conflicted on whether to post. Kind of feels like boasting. I've done some cool stuff, and other people have done other cools stuff.
I'm also not sure of the bucket list definition people are using. A bucket list is a list of life long goals. My list keeps evolving, and I keep doing neat things that I never would have thought to put on the list. One of the coolest things I ever did was to sign off the first Viking Series 400 Twin Otter for its first flight. It was a really big deal, and I'm really proud of what that signature meant, but I didn't really have that on a list of things to do before I die, so I don't think it would really count.
Maybe I'll stop being shy and share a few:
Bucket list type stuff:
Offshore skipper certification
Sailed Victoria to SF
bought own sailboat
backpacked through Europe
lived in New Zealand
climbed grade 6 frozen waterfall
learned to whitewater kayak
(culminating in trip over waterfall, upside down and backwards - oops)
PhD in aerospace engineering from Princeton
rode a century (100 miles by bike)
Mostly I just like becoming reasonably accomplished at things. I'd add sea kayaking, backpacking, mountaineering, rock climbing, and ski touring to the list of things that I've had the chance to get reasonably good at but don't have a specific accomplishment to point to.
Still to go: be debt free, sail around the world, raise cool kids, and most importantly, develop an independent, international, and adventurous lifestyle that breaks us from the 9 to 5. Cruising comes to mind as an example of that.
