Thanks, but no thanks.

Every so often, I take my son to the beach for a nature walk. There's nothing better than finding a quiet strip of sand where we can eat lunch and dip our toes in the water. Usually we come home with our pockets full of shells and rocks and sand, and maybe some beach glass, if we're lucky.

But this? This stayed right where we found it. Ack! I don't even know what it is. Any guesses?
