I keep an online journal on another hunting website I am on. I think a journals page would be a major hit on this site...

I also keep written records in a folder.

I print them off of www.huntinglog.com and keep them in a folder. It records barometric pressure, temp, weather conditions, sightings, etc.

It's a good resource to have if you want to pattern deer movements from past hunts. I'm interested in seeing what the results are at the end of the season.
