That is interesting.
My husband and I have been discussing this sort of scenario and we are fairly certain the exits off the Interstates will be closed by the local LEO and traffic will be kept moving out of the urban areas.
Camps at the end of the route?
In any event, we have spoken about this with friends and everyone is of the same mind: take the chain saw, locate trees and block access where it will do the most to increase local security.
That’s a terrific idea. Had not even considered that (not on the best of terms with neighbors...well it’s more like everyone minds their own business).
Security will be a major concern; especially when time goes on because of growing/raising food; supplies etc.
Like you I get the feeling LEO will “try” to block even the most rural routes. Even if not, it doesn’t hurt to consider all possibilities in the worse case scenarios.
