Recently I found myself along a local stream, sitting on a large tree that had been shoved up onto the gravel bank during this summer's heavy storms. I had fished for a couple hours at this point, having already experienced success in bringing to hand several beautiful wild brown trout. My stopping was for no real reason, since I felt neither tired nor hungry at the moment, but the solace of the trees trunk beckoned me toward a comfortable perch with a view. The morning had shaped up well, with little breeze and only the slightest hint of heat or humidity.
