In reply to Slackboot:
At one point the lambs on one side of a road in Cumbria couldn't be sold because of radiation build up in their bodies, but lambs on the other side of the road could, so deduced that radiation couldn't cross roads. I also recall someone adapting the ready brek advert (the one with the 'glow' around a bunch of children) and using it to entice people to 'move to Cumbria'. Which reminds me of the time when holiday homes in wales were being torched and the advert ran 'Come home to a living fire, move to Wales'. Sorry, mind wandering off topic while trying to write school reports.
