Hi Lindi,
here is a link to a map of your area as seen from space:

You can see most of the north eastern states and Nova Scotia in this map. It may give you some clues where the darker areas are. Sky & Telescope is published in Cambridge, Mass., so I would think they know of some good spots. Here is the link:
