First and Foremost, it makes me feel good. I've always enjoyed fishing, but this is different. After just 1/2 season of ff, I know I'm hooked. I agree with most if not all the reasons cited in previous posts. Two of the things I believe make ff more enjoyable are the level of concentration required and catching a fish with one's own creation. There just isn't time to fret about anything else and I'll never forget how childishly giddy I felt catching my first brookie on a fly I tied.
