I dunno. An island, a space colony....they have some intriguing possibilities (of course, if Mary Margaret couldn't convince a thousand Libertarians to move to Fort Collins, how in heck could 20,000 Libertarians agree on moving to one place?):
Libertarians tried to stage a migration once before. In the late 1980s, Mary Margaret Glennie tried to bring 1,000 Libertarians to Fort Collins, Colo., where she lived. When that failed, she proposed a Libertarian space colony.
