Don't expect to get anywhere in a hurry. After I visited Tintagel a few years ago I was driving along one of those wonderful country roads which are just wide enough for a single vehicle. There was plenty of time to view the scenery as I was stuck behind a tractor towing a cartload of hay for at least half an hour. Eventually it turned off into a farm. Only five minutes later another tractor towing a cart pulled out in front of me and I spent another half an hour behind that.
I can just imagine the first farmer racing to his phone and ringing the neighbour "Quick, hop on your tractor, there's another tourist coming."
