My dad started keeping a journal around 1990 on a calendar. It was basic, keeping stats on water flows, color, techniques used, etc. Starting around 1996 he started a journal on the computer and it reads as a true fish story. It has reports written by me starting around the age 11 and is priceless as far as I'm concerned. All told I believe he's over a 1,000 pages and it chronicles not only us but our fishing network out here on the OP. As a result, patterns have emerged for both fresh and saltwater. Sooner or later he's going to turn the document into an actual bound book.
