Hey chris....hope your well buddy. I am amazed at the spontaneous creation of art like that....I have seen stacked rocks at a place I hunt also. Ill have to take a picture of the conch shell tree.....seems one person put a conch shell on a tree branch (probably as a trail marker) now there are hundreds hanging from this tree. Had a friend ask if I hung a shell there yet....I said no but I will next trip there !! Have a happy weekend brother....catch a carp !!
