Another piece to this are State border crossings in a SHTF scenario. I expect that some States will try to block border crossings so as to keep urban refugees from neighboring States flooding into their State. When I lived in Western MA and my BOL was in VT this was a concern of mine. What I did was study the maps of the VT/MA border and then tested a number of routes so as to familiarize myself with them. Some were just dirt roads going through the woods where I never knew exactly when I crossed the border. except that when I came upon a house the cars would have VT plates. Some of those roads didn’t even have signs identifying them. One in particular had me doubting that I was still on a road at one point. I figured roads of that nature would not be a priority for closing given only local people use them. Now is the time to study lesser traveled routes.
