The difference between Derith and I is that she gets to see more lights in person while I see most of them "on the web"! Sure we may have an advantage identifying some of them due to participation in the "International Lighthouse Game". But anyone can sure solve these, all you have to do is "search"! This is a great game George, now wouldn't you have just croaked if anyone had gotten the answer to this one when all you showed was a bit of breakwater? Although it was a toughie using the ensuing clues made it even more fun to solve.
