Arrived at about 1AM after we had some car trouble. Campground was great because you can pay 24/7 by filling out the envelope at the office and putting it in the drop box. Interstate noise is definitely loud but also heard an owl as we were laying it down. Bathrooms are really far away from the $20 spots and locked after 7 so relieve yourself at a gas station before you get there if you are tent/car camping. We stopped late February and had no issues finding a spot.
