After World War II, the introduction of the 4 wheel drive Jeep and its use in wartime by lots of troops created a rise in interest in off-roading. People were using not only 4 wheel drive vehicles, but body-less cars were popular as well. These vehicles were allowed access to all areas of the dunes and beach complex, from the north end of Pismo Beach, all the way to Mussel Rock, or “Devil’s Slide,” at the south end. Pismo, Oceano, and Guadalupe all had multiple access points, and dune buggies and jeeps abounded in all the surrounding communities. People enjoyed riding on the open dunes, which with no fences to contain the duners and their spirit, gave a feeling of freedom.
