You can see where they've blasted away the limestone rock to make way for the road - the road that leads to the car park at Ballintoy Harbour:
I remember when I was very young, sometime in the late 60s or maybe early 70s, mum and dad had driven to Ballintoy for a 'day out'. Probably it was a Sunday - that's what we did after church. And, as happened frequently in those days, the car broke down. No rescue service in them days, no siree. Dad had to go find a house with a phone and call our farmer neighbour who came out with a tractor and towed us home...not before we told him how to get to Ballintoy. Never heard of it, never been there was his story. It's wasn't that far away from us, about 20 miles. But it was on the coast and a farmer in them days had no business going to such places.
