quiet spaces

["therebesandinmypants" therebesandinmypants]

hello again all
i'm on a project now and i need to record some quiet ambience
tracks [fields, forests, etc]. problem is, i'm in nyc which is one of
the loudest places i've ever lived.
i've rented cars and gone upstate, gone to jersey, and headed south
but i cannot seem to escape the ever-present drone of distant traffic.

are there any places in this north east region that someone can
recommend? anyplace within, say, within 8 hours of nyc?
is there a google map or google earth project that shows quiet areas?
if not, does anyone know how to make one?

as a general rule, how far should one be from a highway to avoid
traffic? 1 mile? 2?

cheers
jeremy
