Yo Mat - yah - for decades I carried a mini-tape recorder on the water and taped lots of comments. It was great to hear the buzz of the reel on a good running fish. I would often pick up clues many years later as I went back through the tapes when getting ready for a trip. That's how I realized how important Yellow Sallies were in the Poconos, which I didn't recognize at the time. No question reliving the sounds of the moment would stir up a lot of remembrances.
But going back through dozens of minitapes got to be a chore, since I had to forward wind and rewind trying to find specific sections. Later, as the digital devices came along, random access became easier.
I had always Excelled (formerly Lotus 1-2-3) a bare bones summary of my trips, listing date, times, gear, catch numbers. Later I added temps, both air and water. Now I have added columns for hatches, rise activity, ffishing notes, incidental observations like snapper turtles and snakes, and comments on the gear setup (I have a LOT of sticks and lines, and I rarely ffish the same combo twice).
