From the book 'Warriors of the Air'<br/><br/>'...Currently, the Pirate-controlled city of Boulder and the 'free city' of Denver are the leading political capitals.' (From 1937)<br/><br/>And, from the Wiki;<br/><br/>'Unofficially, the capital of Colorado is not Denver; rather it is a miniature city, constructed high atop Mount Wausa: Sky Haven. A nest of pirates, bootleggers and criminals, the real seat of power is this secret city. The approach to Sky Haven is precarious; small craft that are not instantly recognized are gunned down on sight, while larger craft (such as zeppelins) must know the precise approach, through narrow, twisting canyons. Failure to negotiate the labyrinthine passageways results in a spectacular crash (and the occasional strafing run from Sky Haven’s inhabitants).' (Late 1938)<br/><br/>So it's a bit of a continuity snarl created by the two video games at least partly conflicting with the original source material; I just think of it as a three-way tug of war, and if any one side wins, everyone loses because then one of the larger or angrier nations surounding Free Colorado will attack and try to annex.
