Click above to watch a great hour-long documentary about the Free State Project (FSP) in New Hampshire. FSP is pushing for 20,000 people to move to New Hampshire and work to reduce the size, scope, and spending of government. More importantly, the 1,600 or so folks who have already moved there are already creating a number of relentlessly interesting and fun communities. For my money, FSP is the most interesting experiment in creating intentional communities I've personally witnessed.
Full disclosure: I show up several times in "101 Reasons" (first time is around the 13-minute mark). I was interviewed at last summer's Porcupine Freedom Fest (PorcFest), which was just totally awesome. I highly recommend attending it to anyone interested in libertarian ideas and community.
