I'm planning on taking a trip across the US and was planning on doing as much dispersed camping (a.k.a.backcountry camping) as possible. I wanted to educate myself on where it is legal to go off trail trekking and camping. I am unsure about the logistics for preparing for this trip. To begin with I am wondering...
What permits may be necessary?
What agencies may need to be contacted?
What areas are likely to allow this type of trip?
Does anyone have some insights regarding what is required to legally and properly go into the woods to camp for 3+ days?
