This is an actual tree very close to the farm. I dare say, I did NOT put my hand in the hole to check it out! But, I do find the image, of the hollowed out opening, very intriguing.
Does it remind you of anything? How about the Bocca della Verita , the Mouth of Truth, in Rome, Italy.
Did you see the classic movie, Roman Holiday, starring Gregory Peck and Audrey Hepburn?
