Who started FSW, and who are the leaders?
Author Boston T. Party (aka Kenneth W. Royce) founded the FSW in order to provide western freestaters with a Wyoming alternative. Boston has purposely set up the FSW as a very informal group without leaders, and without a "cult of personality" ethos. The FSW exists as a sort of glue for Wyoming-minded freestaters.
What is the goal of Free State Wyoming?
To encourage, assist, and reward the migration of liberty-minded Americans to Wyoming in order to maintain and further its relative laissez-faire Western culture; to eventually enjoy a haven for those Americans who desire not to live as, or under, government supremacists.
The FSW is merely an ad hoc group of people who are a) interested in living free/freer lives, and b) would like to do so in Wyoming as good neighbors with the locals.
The FSW is not a political organization, and we have no formal agenda. Our members stand for free trade, political liberty, and voluntary cooperation--that's all. However broad an umbrella that may seem, it is one which covers many different members and viewpoints. Some are religious, some are not. Some are Republicans, most are libertarians. There are probably even a few Democrats.
The FSW will not endorse political efforts, as such has never been the FSW's task. Once FSWers are in Wyoming, the FSW has largely done its job and it is up to individuals to work for freedom as they see fit. They are welcome to begin their own networks and groups for such purposes.
Why Wyoming?
Wyoming was selected for many reasons including its existing culture of freedom; its low population; and its business-friendly laws. Click here for a detailed analysis.
Wyoming does not need improving.
That notwithstanding, its western culture of freedom deserves to be maintained by folks who understand how special Wyoming is. Many FSWers have seen states such as Colorado, Oregon, etc. become tainted by the influx of statists from liberal metropolitan areas, and we don't want to see that happen to Wyoming.
