It was early the afternoon of July 15, 2020 and Sandra Williams and Robert Johnson were sailing their just purchased 2015 Tartan 4700, Du-eT, from Honolulu, Hawaii to San Francisco, California. Sandra was at the helm and Robert was below taking a much needed midday nap. She was hand steering as she enjoyed handling the big boat and the Pacific High winds were such that it required only a light touch. It had all gone smoothly and with less than 250 miles left they were both becoming comfortable with their new purchase and confident they had the skills to handle it. However, everything was about to change. As Sandra held the wheel a wall of greenish blue vapor appeared ahead and seemed to cover everything in their path. She called out to Robert for help and he was in the cockpit next to her in seconds. They stood together and watched the wall approach. Then, just as it touched the boat, it turned into what looked like a pane of glass. A sparkling emerald green bar started to advance crosswise on the center line of the boat. Frightened and unable to move, it passed over them and then disappeared as it went over the stern rail. All seemed unchanged at first, but it had gotten colder, the sky a bit less blue and the water grayer in color. Something had happened that they didn't understand at first, but it wasn't long before Robert began having his suspicions. Sandra was not far behind him in his thinking. She cried out, "It is John! It is John and his group! Robert, how could they do this to us?" Robert knew she was right and he also knew that they, and Du-eT , had been transported back in time. This is when the story of their adventurous visit to 10,000 years before present begins, And this time Robert knew that John would be joining them.
