We found several shark teeth and more in the local gift shop. Really fun beach for kids because shark teeth are awesome.
As a side note, we started the day with car trouble and Mike left before the kids got up to drop our vehicle at a nearby mechanic. We spent the morning getting caught up on laundry, dishes, and cleaning. It gave us a break from all the outdoor action and when we left after lunch, the dog was only home alone for half a day.
