These are links to relevant things that I mention briefly in Chapter 5.

PublicLands.org – The best resource I’ve found for seeing overlay maps of BLM and other national lands.

US Public Lands app (Android/iOS) – A good app for seeing where campable (is that a word?) public lands are.

Guide to Free Campgrounds: Includes Campgrounds $12 and Under in the United States ($15) – I’ve never used this book, but I’ve heard some good things about it. While it may not be the most up-to-date resource out there, it would be a good jumping off point to do more research from.
