I was snooping around Land's End a couple weeks ago and noticed that the octagon house is now vacant. When I worked at the VA someone was living there. I believe I went on a history hike and heard that she was a relative of the last lookout.
It was fun to poke around, I'll post my photos on the Flickr group. If only I had the nerve to climb a tree I could have taken some neat shots of the inside.
