If I were writing a bid to become an Olympic host city, I would concentrate on how the work will be done inexpensively, and how the city a realistic plan to put everything built into productive and permanent use.
A few more of these Billion Dollar ghost towns get built, and people are going to figure out that the Olympics are a boondoggle, and nobody will volunteer to go bankrupt, anymore. The Olympic needs to move to a sustainable model.
Well developed college towns in northern climate zone is the way to go.
