That the whole country is just like the Northeast. (Except even in the rural Northeast there are logging roads and other unpaved roads.)
There are several GPS programs which send people trying to visit us over a Class VI road that peters out and eventually ends in a field of boulders. A couple from Ireland with two kids got stuck there a few years ago.
Yes, in the Notheeast.
There are plenty of forest service roads in the eastern states where you could get hopelessly lost. Tons in western PA and western VA alone. Big difference is that they are lower elevation than the roads out west and do not get the snowfall nor do they get the extremely cold temperatures found in higher elevations out west.
This family was extremely fortunate.
