I'll see your M6 and raise you a Spaghetti Junction (Gravelly Hill) which inspires in me the same tranquil awe, but then again, I don't drive. I love the M6 on the whole really, especially the old service stations, such as the one at Lancaster which looks decidely weird when viewed across the fields from the A6. I wonder, in time, when the cars have gone and humanity has regressed to unprecented savage state ruled over by sentient cockroaches, will they be saying the M6 is the work of God?
