´m still going through the found object photos from my vacation.
This is Shep´s sign:
And next to the sign is the tree:
The strange shoe tree was located in Onalaska, Wisconsin. If you feel like visiting it, a good thing to do is try breakfast at the greasy spoon next door and enjoy your meal with the sweet sound of the wind whistling through the shoe leather.
I asked a few locals, btw, but nobody could explain the tree to me.
"Shep did it, so then other people did it too," was the best answer that I heard.
