I have been to Coos county myself a few times, and I don't think it is a good bug out location for someone in the south. If it is a really bad crisis situation the highways would be clogged with people going north (remember hurricane Katrina) and the Notches (Franconia Notch, Crawford Notch, etc) are bottlenecks that could be deadly. Grafton county on the other hand has the advantages of being half the distance, no bottlenecks to get there, and there plenty of huge empty areas. I remember a Leer jet going down there in the deep woods about 15 years ago where the town boundaries are marked on the topo maps as "undefined". It took two years to find the wreckage, that's how rugged and remote the terrain is. Besides, there are a lot of government listening posts up in Coos on the Canadian border and even rumors (for all the tinfoils out there) of a FEMA camp on Lake Francis (though I find that hard to believe). I'd choose something further south for myself.
