Gold, who works by day in computer network security, posts his images regularly on the community photo blog he operates, Autowitch.org. He's had the itch to dig from early childhood-when his father, a cave photographer, brought him on shoots. But the photo part kicked in only about five years ago. On a trip in northwest Colorado, Gold explored Pinnacle House, an old ruin on a peak along a canyon, accessible only through an underground tunnel. He pulled out his Canon FTB, started shooting, and hasn't stopped since.
