I've been to this spot three times in my life. It's called Pemaquid Point and is in Maine. The first time I went I was just a very small child. My parents turned their back on me and I wandered down that long spine of exposed rock to get a closer look at the ocean. But that day the surf was very rough with massive waves, some of them crashing completely over the rock. Yeah, I could have been swept out to sea.
All I remember about the event are the screams and adults running down to grab me up and take me back to safer ground.
