In the eastern and middle US states, public land may be scarce, but west of the Rockies you can find thousands of acres just waiting for members of the public to happen by.
To find pubic land on which to camp:
- Check official agency websites, specifically the US Forest Service (USFS) and Bureau of Land Management (BLM)
- Stop by the local USFS or BLM office for maps and information
- Ask the locals
