There aren't many easy tips when it comes to fly fishing. As was said before, look into Orvis or any local clubs like trout unlimited. There are a lot of good books on fly fishing. I found the most helpful was "Reading the Water" by Dave Hughes. A fish needs protection from predators, protection from current, a steady line of food, and proper temps and oxygen. Find a place that has as many of these traits as you can and you'll have a spot that can produce consistently. Dead water behind a rock could be good, dead water in front of rock could be better. Best advice, just get out there.
