I just google earthed the Pismo Beach dunes. I don't know why I never realized the dunes were on the beach. I have seen countless sand dune jeep and dirt bike photos of dune racing, but didn't realize there was an area of dunes righ on the water.

That is really cool. If I lived there I would still have my jeep I assure you. Sand just washes off with a garden hose, mudding in a jeep requires far more washing.
