I will NEVER forget. I was at Figure 8 island off the coast of NC and I SAW THE EXACT SAME THING. It was absolutely unbelievable. I watched them for almost an hour. I walked down the beach and went and found my dad and he watched with me! I have to say the ones we saw were further away than these as the lights were not as large, but they moved in a similar pattern back and forth and all around. This was about 9 years ago.
