Bob Sorensen, a golf course assistant superintendent, picks vegetables in his backyard garden at his home in Grand Junction, Colorado. (From the book What I Eat: Around the World in 80 Diets.) The caloric value of his day's worth of food on a day in the month of September was 3,600 kcals. He is 25 years of age; 5 feet, 11 inches tall and 175 pounds. Switching career paths from criminal justice to turf maintenance enabled Bob to escape a desk job and work outdoors in a picturesque Western landscape. Some of his work is physical, but technology makes his irrigation chores easier. From one of many rock outcrops overlooking the lush fairways and greens in the dry, high desert valley, he can control a matrix of sprinklers with a single radio controller. MODEL RELEASED.
