I am in the preliminary stages of planning my 11 year-old son's first backcountry camping trip. I am looking at cabin flats off of the Bradley fork trail in the spring. While my son has no experience with this, I have experience in both camping and navigation (13 years in the Marine Corps reading topo maps and navigating in unfamiliar terrain). Any suggestions/input would be greatly appreciated. In addition I am looking for a good book to get him for Christmas that would help introduce him to the skills that would be needed, again input would be greatly appreciated.
