Married for over 20 years, John and Geri McPherson lived on 46 acres of undeveloped land in the Flint Hills of Kansas. Everything man made on their property had been done by them. They taught many members of the military Special Operations Forces, including A-Teams, Rangers, and SEALs. Twice a year, they used to run a special class on strictly primitive wilderness living and survival skills for instructors from the US Army Special Warfare Command's SERE survival school.
