These sand dunes seem to just come out of now where, and are just beautiful. We dont have ATV’s but there were several people riding around. The southern ranger station (Buttercup, off I-8)) seems to be permanently closed, don’t know about the northern one. There were several RV’s at the camping area, and plenty of room for everyone to camp and play with their “toys”. We read about the Plank Road, which was very interesting. For us, it was just a short rest stop off I-8, but I can see why people would stay for a while and camp here.
