Call walked the river for an hour, though he knew there was no real need. It was just an old habit he had, left over from wilder times: checking, looking for sign of one kind or another, honing his instincts, as much as anything. In his years as a Ranger captain it had been his habit to get off by himself for a time, every night, out of camp and away from whatever talking and bickering were going on. He had discovered early on that his instincts needed privacy in which to operate. Sitting around a fire being sociable, yawning and yarning, might be fine in safe country, but it could cost you an edge in country that wasn't so safe. He liked to get off by himself, a mile or so from camp, and listen to the country, not the men.
