I'd love to go to Japan. I like the idea of placing myself someplace just so completely foreign (yet still relatively safe, since I am a giant pussy). Also, I love the idea of towering over everyone. And I like electronics.
Highest - well, not so high - half-dome in Yosemite. But we free climbed it on the face - so that makes up for the height. Let's see, it is 4,737 ft high. I have climed the trail about 5 or 6 times and climbed the NW face once (at 20 yrs old)
