I'm like Greg. I like being able to say (without guessing) how many of each animal (age/sex) I saw last year....2006....etc... . I like being able to recall the dates I took bucks on (although I can do that off the top of my head). I like knowing how many deer I avg. seeing/sit.

Do I use it to tell me where to hunt? Heck NO. Do I take note if a particular spot was "hot" at a particular time of year? Yep. Would it make me chance a wind to go in there? No.

It's just interesting fodder, for me. And you're right.....3 yrs from now....if I'm hunting the same property....it won't aid me at all (other than trivially).
