The Statement of Intent.
"I solemnly pledge that I am able and willing to join the Free State Wyoming and its effort to populate
Wyoming with individuals of demonstrably ethical character who ? forsaking fraud, theft, and
aggression ? desire to peaceably co-exist as reasonable neighbors for the goals of political liberty, free
trade, and voluntary cooperation."
In other words, you've got to be a libertarian to join. Or at least you have to pledge to behave like one.
