I prefer to keep a journal of all my fishing expeditions. From inshore saltwater to tailwaters and of course many trips to the park. I don't count or keep track of fish numbers but I do keep up with the number of days that I fished on the year. Many times I will write my entries later at night reflecting with a couple of beers, makes for some fun reading when you look back. Plus as many places and types of fishing that I do, all on the fly, you can sometimes forget important imformation regarding different rivers patterns etc...which the journal can help.
