About all I know about fly fishing is that it can be done in fresh or salt water.
That's for sure. I quite like to fish, mostly in saltwater. My favorite fish to catch is called a Snook.
So there is a different rod that must be used, a fly rod?
Yeah a fly rod is different than a spin rod. The point of a fly rod is to cause your lure to land on the surface of the water like a fly.
I find it interesting that many lures are hand tied by the fishermen.  Do you do that?
I've tried it, but it is an art that would take years to master. I know a guy who goes out to a stream in the early morning to see what flies have hatched and ties flies that look like the newly hatched ones.
That is a really dedicated person to make artificial flies like that!
It really is. For some people, fly fishing is like a form of meditation. Cold mountain streams, crisp dry air, sparkling rainbow trout. It's no wonder they find a spiritual connection.
