Pagan

I have no idea if they are pagan or not, but in a field on the way to work and with the sunrise in the east, I stopped to blip. Intrigued that the the indentation on the stone is incomplete, and does not go all the way through, so I wonder what its significance or purpose is. But it's there and deep both sides of the standing stone.
I wonder if in years to come people will look in wonder at Blip and ask what it's significance was?
