Another WELCOME from another ex-Navy guy! I think we really appreciate the function of light-houses, along with their beauty! I was black-shoe, 1105-Lt(jg) who never set foot on a ship! But thanks to the Navy, I ended up with a great career in computers. Now I work for Lockheed Martin - we install engineer, integrate and install the FAA air traffic control systems that keep you guys from bumping into each other up there.. :-)
