One day at work we spotted a caribou lying in the opposite end of a dry pond from us, so I got out the passenger door to see how close I could sneak up on it. I slithered along on my belly, taking my time, and 20 minutes later I was close enough to kill it with a knife. Another time I was lying on the side of a knoll and a small herd or caribou fed right up to my boot. One summer day we were walking along an esker with the wind on our backs yet, and this dopy caribou came walking towards us with his head down and would have bumped into us if I hadn't spoken softly. That dummy is lucky Shadow wasn't a wolf. Polar bears don't have to be snuck up on, often they are quite willing to close the distance. When that distance closes to arms length, that gets your heart going.
