I like the work you have to put into it... provides satisfaction on a good day out. Whether it be tying your own flies, building your own rods, furling your own leaders, learning more about fishing this way and applying it on the water... all of that. When they come together and you catch a fish on a fly you made, on a rod you built, with a leader you furled using techniques you read about and practiced in the field.. fabulous feeling!

Not to mention the places the trout live. Doesn't get much prettier out in the great wide open than that!
