For John Humphrey, childhood used to mean having fun in the backyard of his home in New Jersey. “We had a rule that we couldn’t go any farther than the bell or the sound of my mother’s whistle,” he recalls. “I was always digging and playing.”
Then Humphrey went to a school that offered a Boy Scout programme. “I just loved the outdoors and this particular troop camped 12 months a year. It didn’t matter – winter, snow, ice, hot – I loved that part of it.”
