Collecting rocks from shore

"Dad, guess what I have in my hand!" she shouted as she swam back to the boat... "I caught a frog!" I wasn't sure, but if there was a frog involved, she was carrying it underwater for quite some time, so I let her know that they do need to breath. She made it to the boat after holding one hand up to pretend to let the frog breath, and plopped a 5 pound pink rock on the ski deck of the boat. She had hauled it all the way from shore. Pretty crazy. Then she went back for more, and brought up quite a collection of interesting rocks that she dug out of the clay banks on the shore. Cal then followed her in, and got his rock most of the way back before dropping it.
