I keep a notebook full of notes. I guess you could call it a log. I write down where I' ve seen rubs, scrapes, trails that intersect, when I kill a deer I write down which way the wind was blowin, day of the month, time of day, etc. all I have to do is go back over my notes and pick a stand that matches up with the info above. it helps a lot when you can' t remember like myself.
