Harry,
Yes, a pretty big road by local standards. This is the road across the Lammermuir Hills, looking north towards the Firth of Forth. You may be able to make out Traprain Law (the hill directly ahead), North Berwick Law (to its left) and The Bass Rock (the white island to the right, which is covered in gannets). These are all volcanic remnants. Edinburgh is 20 miles to the west.
