One of the most pleasurable things an Elephant can do is have a good long Scratch after being in the mud, this relationship with a piece of old Stump, sticking out of the ground is like a love affair, he caresses it with all parts of himself and rubs and rubs and rubs, the pleasure is palpable. After many years these beautiful stumps turn into incredible polished reminders of the relationship that has been had with it.
I personally think that Elephant Scratching posts are underrated.
They should be considered pieces of art created by nature itself. They are found in the most beautiful existing museum, that of the bush.
