We just found one of these. It had a wooden bunny, a notebook, a rubber pigs nose, a toy car and a bobblehead. Along with a little note explaining to go to the site.
I was laughing because this guy was outside our window and looking at this tree straight in this empty field next to the house a few weeks ago. He acted so strange that we called the police on him. Now I am LMAO at the treasure we found. How funny is that? Go on a treasure hunt and get the popo called on you.
We added a photo and a poem on the back and stashed it away.
