I keep a log of how many times I get out, whether that means out with someone in their boat, or just to the pier, and how many times I get skunked. I will make a side note with the date when I catch my first yellow perch of the year, usually an itty bitty lil thing I throw back, and then when I've caught the first yellow(s) worth keeping and I'll mark any date that I've had a really good day. I don't get into what bait, or depth (when I've been out in boat,) or anything like that (because I usually don't know), just how many I caught, what species they were (a fish is a fish and I count'em all, mainly for comparison's sake the following year and for those days when my son decides to contact me to let me know he went fishin when I perhaps didn't, and he wants to try stick it to me about how many he's caught. You know the friendly, yet not so friendly competition of who has caught more. With him, I have yet to lose that contest.)
That might change when the day comes that I have my own boat, then I might be a little more interested in depths, baits etc but for off the pier, or out with someone else in their boat, all I need to really know right now is how many I caught, how many I kept, and the date because it's a pretty safe bet that if I'm talking perch we all know what I used for bait and if I'm out with someone else in their boat, pretty safe bet that whomever it is I've gone out with probably is using the same lures as everyone else.
