I think small towns are ideal. I’m about 70 miles west of Detroit and better than 10 miles off the highway. There are other little towns every 4 or 5 miles in every direction.
Any urban barbarians who think they could simply roll out across the country side taking what they want would be in for a big surprise.
(you’re gonna let us in if the SHTF, right? I’ll show my FReeper ID, live in our camper and bring cookies)
