The sand castle doesn't look nearly as impressive on camera.  Maybe it's the way the light is bouncing off the sand or could it be the paper cup quality to the architecture.

We tossed the Nerf football around and people stopped to stare.  A couple of people even stopped to ask if they could try throwing it.  Football is a novelty here.  Everything about us said "We're Americans."  We were the only people on the beach without bikinis and speedos.
