That is a good idea that you have Daniel. What I plan on doing is make a digital Photo of all my Harbour Lights then place the photos onto a DVD and keeping it in my fireproof safe. Not being too computer savy, can you add photos to an existing DVd which you already own? I am thinking in the future when I get new Lighthouses to keep them all to gether on the same dvd. Does anyone know it this can be done?
