In the bookstore I found a great book about lighthouses called American Lighthouses. I probably should have bought it onsite, but intend to order it when I get home. However, after our visits to other sites since this one I've learned how many lighthouses there are in the northeast. There are an incredible amount of lighthouses!
The pano image of the navesink lighthouse was stitched together from many images taken with an iphone. Pretty incredible for a phone eh?
