We are currently residing in Intercourse, PA.. There is a working Amish farm right across from my RV. They are TOTALLY self-sufficient; no engines, no electricity. If society collapses, will the Amish be the last surviving American community (key word is community, not individuals)? I don't know if they arm themselves in case of encroachment, but I do know this farm has three large dogs patrolling it, and I would not venture onto their land. If our society ever collapses, I will try to make may way back here to protect them, and will defend them to the best of my ability, for fresh eggs, bread, and a slice of Shoo-Fly Pie.
