Although I enjoy reading your books immensely, you may (haha) be interested to hear that when I was confronted with the seemingly impossible task of raising my garage door lintel into position alone and unaided, I remembered “Stonehenge” and with a pile of concrete blocks, up the lintels went – 4 inches at a time. It took a while but I am indepted to you for the story. Regards Colin Naylar
