I first heard about the Free State Project from a slashdot story in October 2003, when they announced that New Hampshire was the target state. At the time I was on a 1-year work contract in Australia, and all I knew was that when I returned to the USA, I did not want to return to the high taxes, high population density and (comparatively) bad air quality of the Bay Area. As a libertarian myself, it was a no-brainer, especially after I read the "101 Reasons to choose New Hampshire" document (which has subsequently been turned into a video documentary). So I went back to California just long enough to make arrangements. I moved to NH in June 2005, making me mover #107.
In the time I have been here, some 1,900 other "early movers" have also come. We have gone from electing a few Free-Staters to local city councils and planning boards, to our first State Representative, to now having some two dozen Free-Stater State Reps, and having pulled many of the existing State Reps and Senators (especially the Republican ones) in a much more libertarian direction. I will never forget the ex-Marine State Rep who in 2006 told me he would "never, ever in his life" allow "legal dope", to that same Rep now voting for full marijuana legalization every single time it comes up. We were the first state to pass same-sex marriage via a legislative process (not popular referendum). We passed medical marijuana. We have no adult seat belt law, no helmet law, open carry and shall-issue concealed carry (and are likely to pass constitutional carry next session). We have eliminated all state knife laws, absolutely rejected Real-ID ("and any de-facto national identity system that may follow therefrom"), forbidden the State to use automated license plate scanners, and passed a law affirming a defendant's right to explain Nullification to the jury.
We don't need all 20,000 to show up. Another 4-5K people, if they do the same things as the first 2K, and NH will bear very little resemblance to the police-states/welfare-states of the rest of the USA... and much more resemblance to the society described in the New Hampshire Constitution, which is summed up well by Article 10:
Government being instituted for the common benefit, protection, and security, of the whole community, and not for the private interest or emolument of any one man, family, or class of men; therefore, whenever the ends of government are perverted, and public liberty manifestly endangered, and all other means of redress are ineffectual, the people may, and of right ought to reform the old, or establish a new government. The doctrine of nonresistance against arbitrary power, and oppression, is absurd, slavish, and destructive of the good and happiness of mankind.
