Yellowstone caldera? Pffft. We've built our largest city (Auckland) on a field of some 53 volcanoes.... and Taupo, just 3 hours drive south of Auckland, is the site of the largest volcanic eruption the world has seen in the past 70,000 years (hmmm, maybe we Kiwis are just not very bright). Very scenic at the moment though....
Your post reminded me of a George Carlin line on that subject given during a dissertation on messing with nature. He said something close to:
"And then there are people who build their houses right next to a volcano and wonder why they have LAVA in their living room."
