Racing River Dispersed Camping

We stayed one night on the way back down from Alaska. Beautiful spot on the river. Nearby bridge is made of metal and can be heard when vehicles cross the river. Lots of room for big rigs like ours to get in and positioned. A few roads off the spot we stayed at would be perfect for truck campers and vans for more private spots. There was no cell signal here even with a booster. Fire pits at sites.
When you pull off the highway there is a rest area with garbage bins and then the road that leads back to this area with camping spots.
Just up the road from here if you look on google maps you will see a few other gravel roads leading to river with more places to stay.
