OK, just a cheap way of getting a name check for my home village that wouldn't otherwise have a chance of a mention here....
an article about all the crop marks appearing everywhere
http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/08/21/nfootprints21.xml
including one at Claverley -
"Deep green crop markings photographed at Claverley, near Bridgnorth, Shropshire, showed up parallel ditches in a field of sugar beet. They probably surrounded a late prehistoric settlement."
No big deal to you lot no doubt, but to me, brought up in a megalithic desert of soft red sandstone and river gravel, without the least sniff of anthing prehistoric, MEGA!
