In dispersed camping areas there are no facilities and no hook ups which works good for me. Most dispersed campsites are found along secondary roads. They are often off rough gravel roads and the sites are not always marked. Popular locations often have the telltale signs of previous campers like a fire ring made of rocks.
The government website suggests if possible, use existing sites to avoid creating new disturbances in the area. To protect this public land, campers have to pack in water and pack out any garbage or waste. Obviously it is important not to pollute these pristine areas so the sites stay clean for all of us to use.
Through Washington and Oregon I stayed at rest stops or truck stops as I was mostly travelling along major highways. Generally I found these were easy to access, safe, and had good cell reception. My first dispersed camping spot was outside of Moab in southern Utah.
