I keep track of my days fishing a little bit differently. I use my Outlook calendar at work. I have one calendar for meetings & another for keeping track of my fishing experiences. I check my meeting calendar every day so it's easy to update my fishing one. I update the day after I fish. I just go to the date I fished, open it up like I'm going to schedule a meeting and then enter my info. I put river / pond fished, where on the river I fished, how many fish I caught and what I caught them on. I have also started adding comments about hatches observed, who I fished with etc. At some point I will add air temp., water temp, weather conditions etc. I find it easy to use & review.
