Just for clarification, what is the cut off for young/old. And, OK might as well define fat too.
For me I will kayak the Great Slave Lk soon.
Trek Patagonia.
Climb in the Huayhuash

+1 for trekking Patagonia.
And, not a huge adventure (1 day only), but kayak across the Salton Sea, which I'll do early 2011. I've heard that I'll look like a glazed donut afterwards. Got shower?

I would love to see the Himalaya and do a short trek there. And raft the Grand Canyon but that's not out of my venue as some of you know, just not in my checkbook I want to see Yellowstone in winter when the tourists are all gone and cross country ski across the frozen lake. Bali or Tahiti for two do-nothing but swim and explore weeks has always been a dream. And I want to do all this soon soon soon soon especially when I have a rotten day at work!
