I'm from Nevada and this is one of my favorite places to camp in the summer.
My only complaint is that people throw large amounts of toilet paper in the bushes everywhere. I have a silly little youtube channel called Adrenaline Jackie where I pick up litter with my dogs but I really don't enjoy picking up people's nasty wet wipes. Please bring a few bags with you to throw the TP in!
There's a True Value hardware store 2 miles or so away that really has everything you need if you forget anything for your trip. They also have a good selection of groceries for a small town store.
Some of the roads in this camping area are pretty rough for a regular car. I think the roads are passable with a normal car and some driving skills in most areas but be prepared to turn around or back up for a while. If you must bring a car, just take your time and be mindful of how high your car is so you don't rip the front off. Have fun!
