Extremely helpful when roadtriping to find campsites. One key note I've found. Just because a campsite is on the map doesn't mean it's open. I've learned that the hard way many times now. Dyrt makes it very easy to go to the campsites website and check for availability.
Easy to pay and very clean bathrooms. It was very windy and rainy the night I stayed. I slept in the back of my old 4Runner and it felt like I was on a boat at times from the rocking of the car in the wind
