Everyone has their own style and urges to either stay at a spot for longer or move on. Over the years I have fished with countless other anglers. I have never seen two anglers who move at the same speed. Slow or fast, does not matter. It all depends on what makes you most comfortable. I would have to say that I tend to move faster than most. Usually, the river we are fishing is a river I know well. Since I know it well, and know what is up ahead, I usually move at a fair speed.
Plus, I am totally a type A individual. Many people (including my wife) have indicated that when I am walking, I move as if I am powered by a motor.
