This answer changes on a nigh-weekly basis. I wouldn't want to leave right this second (because my bags are packed for yet another trip to Los Angeles--I leave at 5:00), but at the moment, I would love to take a week and see sakura season in Kyoto.
Call me next week for where and when I want to go then. On the list of recent places: my hometown for a week, Sydney, a number of cities in Europe, a spiritual retreat on Mont Athos, and a trip to the Pacific Northwest. Further back, you'll find an interest in Carnivale season in Rio, a trip to the South Pole, and a few dozen other places. In midsummer, I might even say that I want to go backpacking in Siberia, but that will be the heat getting to me.
