I keep a journal of every hunt including:

Stand location
Wind direction and speed
am/pm hunt
Barometer
Moon phase
Temp
Cloud cover
Techniques used for the hunt (rattle, grunt, etc.)
Bait or no bait down
Sightings

There are some good programs available out there for around 30 bones that log each hunt with very similar info. After a few years, you would have enough info to be able to input the upcoming hunt's conditions and the program would recommend which stand to hunt from. Can't remember the name of it, I'll look it up. I plan on getting it this year.
