I have never done the premade sheets or too specific on my notes.
Basically every fish picture I have ever taken is on my computer foldered in the years they were caught. Then some notes are taken on a Microsoft program and dropped in the folder for that year if need be. Most of the time I can remember the details just by seeing the picture.
Funny, I can go back pull up details of a fishing trip back in 2005 by looking at a picture but forget to throw clothes in the dryer.
