Thanks - this link will wake up in six or seven weeks ( http://www.cropcircleconnector.com/2008/2008.html ) when the first ones appear. There will be a rational explanation somewhere but the increasing complexity of the design suggests intelligent action - perhaps. The 'research' button on the left of that page is active and has 'more stuff'. Strangely, there are more people with my surname in the United States than are left in Lancashire. They got out fast and landed up on the eastern seaboard. I think my namesake has a plumbers' supply business in Indiana!
