I tried to help search the sand for whole sand dollars. They were more difficult to find that broken pieces. They usually remained whole when they were partially hidden in the sand. So you could only see a small white flat circle sticking out of the sand. I saw something that looked like part of a sand dollar. It was small and white and flat and a circle. I called to my 7 year old and said, "It looks like a sand dollar over there."
He looked up and over to the spot where I was pointing. He said, "No mom, that's just bird poop."
Ahhhh... Nothing like a day at the beach.
