I stayed at one of the primitive tent sites. It was nice and shaded. As the other reviewer pointed out, further away from the entrance will get you away from the road noise. The shower house was very clean and well kept.
I would definitely stay here again. I would just select a site toward the back.
If you can get a site in the back, they look really great. We had a site in the front which is right next to the highway so it was a little loud and we had no shade.
