Looking at the video Basia would be screaming at the driver "Do not go so close to the edge!" I have heard it in my ear - often, on the mountains of La Palma and Madeira, as well as in the Pyrenees. She forgets that we Arto drivers take care of our precious steeds.
Which is why she refused to go on that train when we were there, much to my disappontment. We did go on the Romney, Hythe and Dymchuch railway - in the Queen's carriage - but that is all at sea level
Tell Jayne to enjoy it.
