We came out in our van on a Saturday around 5:30pm. Lots of spots open and we ended up at one right off the road- that was a mistake. The road is very well maintained and smooth and so cars drive really fast down the road creating so much dust!! We regret not following one of the side roads to find a spot away from the road more. We were sneezing and felt pretty dirty from the dust by the time we left the next morning. We could see two other groups from where we were, but we were in a van so we can’t hear any noise at night so that was fine! And it felt like we were far enough away too. Not sure if there were lots of ATVs or off-road vehicles on the road at night because, again, we can’t hear anything when we’re sleeping in the van. Overall we will probably be back but definitely we will not park right off the road again. It looked like even some people parked off the road about 400-500 feet were getting dusty too, just not as dusted as we were. I had Verizon cell phone service the whole time!
