If you live in key West, you probably have never seen any thing in the past 10 of the 12 years. I have been in Key West many times and I have seen the Green flash many times and have seen it in the bay north of Key Largo and have seen it every day, when looking for it, in Hawaii. Elevation helps, when in Hawaii, I watched from an elevated porch, it helps to remove clutter on the horizon. To let everyone know what to look for: look at the last instant of the sun ball, disapearing over the horizon.
