What separates fly fishing from all other forms is a heavy reliance on casting, a rhythmic, repetitive motion that puts the fly in play in much the same way it was done 200 years ago in England. Fly fishing is very, very big on tradition. Getting to that plane beyond the pain, though, as with all aerobic sports, is a matter of mastering fundamentals to the point where they aren't even thought about, they just happen. WHAT NOT TO DO Don't be intimidated by all the weird but strangely attractive equipment and a pervasive mystic that suggests only the select can succeed at fishing with flies. A corollary is not to rush into a sporting goods shop and outfit yourself before you have the faintest idea what's needed for the specific type of fly fishing you'll do.
Nobody wants to get fleeced.
But that's what you're setting yourself up for by letting any enthusiasm for the acquisition of equipment override common sense. And it's a toll road all the way. What you need first is a good guide. That's in a generic sense, although down the line the learning curve can be dramatically shortened by hooking up with a pro who is experienced in coaching along beginners. The overall problem about getting into fly fishing is that until you know a little bit about it, you really don't know enough to ask meaningful questions or compute the answers you do get.
