Anyone who's gone to see Cape Neddick Lighthouse in York, Maine, better known as the Nubble Light, knows that very few people get on the island -- most view it across a narrow channel from Sohier Park.
I was lucky enough, back in August 2003, to get the opportunity to get on the island with two Coast Guardsmen who were inspecting the fourth-order Fresnel lens. I might never get on the island again, so I treasure the memory of that day.
