What's wrong with that? From what I can tell it's a very beautiful state. Certainly far better than living in Oklahoma or Ohio.
It is a nice state to visit, no question. But there is not a lot to do there once you have seen the national parks and been to the rodeo once.
I guess as part of this plan the best thing to do would be to airlift the entire city of San Francisco (complete with all the buildings and their foundations) into the middle of Wyoming, so that all the Californians would not immediately want to leave again.
That would change with an influx of population. Wyoming is one of the few states actually losing population right now and has been doing so for at least two years in a row (

If the hypothetical influx of Californians you all mentioned moved there, things would change fast. Heck, Cheyenne would finally have over 100,000 people lol
