Well with out Hoover Dam, Las Vegas would not exist. For good or Ill its done the money spent, its like crying over spilled milk. Early this summer I was out at The Grand Coulee dam, in Washington State. Its high desert yet the whole area is a giant fruit orchard. Never mind the Electricity the country need on the eve of World War II Hanford is not to far. Yea they lost the salmon runs while I would rather fish, I also like a steady supply of Apples and Cherries too. Its something to see, and if it was not there or built there would be a whole lot of nothing there. Thou where I was for a few weeks outside of the orchards, there was a whole lot of nothing.
