When I started fly fishing I never wrote down my experiences on the water, committing most to memory, but as I gained a few more years on this earth, and many more fishing trips, my memory got a bit fuzzy and what particular fly worked on May 6th, in rough water was no longer easy to recall.
Thats when I started writing down certain facts that related to a fishing outing, the only thing most of what I wrote down was on index cards and cheap pocket small note pads. These notes were soon lost and I was back to guessing. Thats when at a fly show I discovered journals just for fishing.
This made my trips documented and organized. The first journal was a nice hard cover book, the only drawback was it was not easy to take with me.
I used to write down my entries when I returned home, so as not to forget.
I soon found a small journal that would fit in my pack and I could document my thoughts and results right at streamside.
I still carry my journal, although not every outing has a page. I now reserve some of my special trips to document.
I also keep a small journal of the streamer patterns I design, with recipes and results when fished.
