Progolf, no problem. I learned this valuable lesson from Royal Coachman and Fish Finder who I had the pleasure of fishing with. I sat there getting skunked all day while they nailed fish after fish. It was an extremely humbling experience and made me realize that the problem is often on the reel end of the line and not on the fish's.
Granted, there are tough days but far fewer than I thought. Most of the tough ones I had experienced were such because I made them so. Wrong depth, wrong time, wrong retrieve, wrong place on the lake and last and least common, wrong fly. Worst of all was that hard headed approach that the spot and fly I chose must work because that's what's supposed to hatch at a certain time of year on a certain lake. Every day out is a puzzle. Taking the time to truly look around and see the signs will get you into fish faster and in the long run, save you time.
In any case Rieber, the Plateau area lakes will get steadily better the closer to September we get. Avoid full moons and unstable weather, look for weedy fishy looking waters with lots of bugs and shucks near the shore and you'll put the hurt on them.
