I put the two lighthouses out there, but I bet nobody goes to see them either, one is 2400 miles from Ketchikan! I'll probably not play with SPBs on those islands. I was looking at ones nearer to home like Point Baker and Protection Point, etc. Baker is beautifully laid out in Google Earth, so that definitely needs an SPB.
But again also, I'm looking for errors (like the water up the dock at Nukati Bay Dock, those I'll go back and fix for us.
