Before locking yourself into a bug-out plan, make sure that the bug-in option isn't better. Bugging out is a last resort thing for folks with family -- extended family. My bet is that when the time comes, there will be a lot of hungry inexperienced peeps in the White Mtns.

Bugging in keeps the roof you have over your head. Food is in the pantry. For which scenarios do you intend to bug-out? How about dead of winter? Make that hungry and cold.
Bugging in may be a better option for all but the most dire scenarios.

my opinion, YMMV
