I was past the point where I could hear cars or people.

As a general rule, the pools and deep runs that are within a short walk from the parking lot get fished hard. The water looks great. It seems like it might be productive. Styrofoam worm cups and Bud Lite cans are often serve as the fishing report. Only five or ten minutes up into the mountains and things change. The literal quiet is accompanied by a sense of quiet. The trails get narrower. The signs of people disappear. Then, there are fish.
