You are most welcome Guenn .. you know when i read your story it occurred to me that it may have been placed there by a child/ren .... but yes the possibilities are endless. I also thought it may have been stolen by someone and they needed to hide it quickly and never had the opportunity to retrieve it ... I can imagine the surprise your son experienced when he first noticed it and yours when he opened his hand to show you ... it definitely found its rightful home with you all these years later ... a reward for nurturing and appreciating the tree during its lifetime maybe
