I’ve been going to the exact same spot on the exact same NC beach for over seventy years. It looks exactly like it used to.

I'm presently sitting on the beach on the Texas gulf coast.
I have been coming down here since I was a child some 60+ years ago.

IT HAS NOT CHANGED ONE INCH with respect of where the beach and water meet. The distance to the dunes has not changed. There is ZERO evidence of subsiding or retreating sand.
