I've been several places. I've been over a great deal of Europe and South America, a good deal of North America, Russia, and Australia. I really want to have some time to do studies in Japan and Asia though due to their recent fortean events.
Like Ski, most of what I learned was about people. However, it did solidfy my belief that the RE model simply does not add up. It also lead to several chapters worth of material that may be devoted to historic mysteries explained on/by a flat earth.
