The first account in this series of remarkable events in my life that do not fit with the scientific materialist worldview, which is currently prevalent, happened when I was 11 years old. I was on a scout camp in a huge field surrounded by woods, across which ran an ancient hedge that over the centuries had flattened off into only a ridge and dip in the land. A single huge oak tree remained half way along it. The Senior Scouts had arrived before us and set up a death slide from the tree, with a zip wire from high up in the branches down to about 30 meters along the dip.
