Fisherman will sometimes offer a reluctant little wave as an artificial courtesy when one boat passes another. But this is nonsense.
Hunters are the same.
The rest of us, recreational outdoorsmen, will pass on trails and merely nod. Or say nothing. All of us march around outdoors as if we own the place, nobody acknowledging the next guy, resentful of the stranger who merely happens to be a guy who is also marching around the outdoors as if he owns the place. He had invited a total stranger to hunt geese with him that day. Above him in the gray the snowflakes fell everywhere, soundless, falling on the three dozen decoys he and the stranger had arranged in the dark earlier in the snow-covered field.
