Indeed, they actually tend to bite a bit more once the sun comes up. The only reason I am there at the crack of dawn is so I can fish for a few hours as I usually have to be home by noon so the wife can go to work. It also helps to get there before any one else as it is not as easy to fly fish crowded runs. Did not help me yesterday as I was the first at one run and by the time I had set up and cast, there were two more guys working the run including one that came in right under me and basically left me stranded working the same part of the run until I decided to leap frog him. He was apologetic, claiming there was no where else for him to go as the other guy was already fishing the lower end of the run. I contemplated explaining how all need he needed to do was ask me how long I had been there, and if I was planning on working down the run, or he could have waited a few minutes to see if I moved down. But I just shrugged and told him not to sweat it and continued down the run below him and then headed down to where DRP79 got his fish. I had that run all to myself for the most part, at least on my side of the river, that is until someone else came in below me and fished the tail out before I got to it.
