Just was interested in what led the decision in basing the world of Xsyon in and around Lake Tahoe. I must say it has turned out quite astonishingly beautiful, but I'm simply curious as to why Tahoe turned out the basis for the world versus say Yellowstone, or Yosemite or any other myriad of breathtaking areas. Any conjuncture, suggestions or answers?

Cheers
