The initial campground was definitely an RV only type of place as there was no coverage to take care of business.
But if you keep going up the road there are more than a few turnouts worth staying at for those of us with tents.
We found a decently sized one roughly 4 and a half miles up the road. Beautiful view over the valley, large enough area for multiple cars. Spotty 1 to 2 bar LTE coverage.
