Quick update, about half way thru the challenge and I am a bit ahead of schedule to make it, full list of lighthouses should go up by next weekend, then I will take one more three day tour in the spring up the arm of the cape and that should do it for me
More are coming, took a bit of the winter off being in New England but hit 3 more lighthouses over the weekend and I have a trip planned for next week that will get me almost to where I need to be. Heading up the coast into Maine and back hitting a bunch of spots, should take me 3 or 4 days total.
