I saw another thread about the best place to bug out to, and I thought the idea of one single best place being best is silly. A bug out location is most useful when you are actually able to get there from where your job and life necessitates that you live.
Next to the logistics of getting there, which is the number one concern, one of the most important elements for me is population density.
I love people, but city dwelling requires networks of systems to work and continue working to maintain and the city is the worst place to be in a SHTF situation.
So I wanted to share this interesting link Defining America: Exploring the 2010 census - CNN.com
Its the US Census data from 2010 sorted into a map format. For me it convinced me that a few counties in Vermont, New Hampshire, and Maine were my best bet. It also made me reconsider my evac routes considering alternate routes based on population density. (Look at "census tracks" for the most localized pop density figures)
Of course resources and local politics play a role too, but I wonder how your bug out location, be it your home (Shelter in Place) or a cabin rates?
