If you can flick a tater off of the end of a fork, you can fly fish! I learned how to fly fish through books. I have lots of them and they are all fun to read, Fly fishing has become some kind of fraternity that only fly fishermen understand, and there are so many ways to explain it, often times using humor and just common sense that applies to everything in life! SO, the next time you are at the used book store.....I highly recommend books about the sport and these men who actually think they are smarter than any fish- and often times mistaken!
So, the trick to flyfishing is learning how to false cast until you have the distance and correct angle to present your fly to a fish that you already know is there- WITHOUT SPOOKING HIM AWAY!
If you know what to look for and where, you can find trout just waiting there for their food, that are very hungry.
You can always use what they call an attracter fly, like a wooly worm for example that a lot of trout just can't ignore.
But most trout have a certain food that they eat the most, and those will depend on the area and what mostly naturally hatches out in the water you are fishing in!
