The idea of independant militias or bands of patriots roaming the country makes me think it is someone's idea that the US is going to completely fall apart, and the gun-owners of America will have to take the country back, house-to-house, one town at a time, engaging in massive firefights along the way. If such a thing happened, (the US collapsing entirely, not the house-to-house fighting civilian wet-dream) I think a more realistic result would be towns banding together to survive, and forming a psuedo-milita to reinforce the LE, and provide an additional layer of defense from road gangs, an unfortunate eventuality. If you are really interested in what your neighbors have, that's the time for some good 'ole meet and greet, or community organizing, not online polls canvasing the entire nation.
I, for one, might migrate to a warmer climate, but I would not be roaming the country, cleaning up each town along the way like some Clint Eastwood character. If the entire might of the US military cannot do such a thing in a country a fraction of the size of the US, how could one man, or small, marginally trained at best, groups hope to accomplish the same result?
