Ok. Most of the lights were built about the same time in that part of Maine. Owls Head is up the coast a bit outside Rockland. I was in Bar Harbor recently - went up on Cadillac Montain before sunrise to be the first in the United States that day to see it rise over the Atlantic. That is - along with about 300 of my closest friends. Everyone was up there - very moving experience. My ancestors come from the central coast of Maine - mostly Vinalhaven Island. I was born in Presque Isle, Maine.
