After my first encounter with a mature buck, the beginning of the addiction, I started reading. I read every forum I could find. I tried to find the most popular references to books and videos from people that weren't out to push advertising down your throat and bought them. I joined the forums and started asking questions. The one piece of advice I kept coming across from the reputable authors, hunters, and forum members was the importance of post and preseason scouting.
About this time I started having to travel for work and wasn't able to spend much more time in the woods that season. The travel continued after season and into the early spring. I was very disappointed that I wasn't able to get in the woods and start scouting after the season ended. This seems to be one of, if not the most, critical part of scouting. I kept my head up and started hitting the woods as soon as work allowed, which was late March time frame.
I glassed fields in the evenings, walks hills in the mornings. Found travel corridors and pinch points, last years rubs, secluded patches of white oaks, funnels, etc... All of these things I knew absolutely nothing about a few months ago. I saw more deer sign than I had in my 6-8 years of hunting prior to that. I was pumped! I found trees that looked to be absolutely perfect kill spots, and they were, except for the wind....
That was the other thing I found in ALL of my research. The importance of hunting the wind. This lead me to thermals and the effect of obstructions, openings, hills and bodies of water on the direction of wind. after finding the predominant wind directions and doing my best to account for thermals and swirling I picked out a bunch of trees as possible climbing trees, but decided I would remain open to other trees in the areas based on wind and other intel. Then I had to try to find good entry and exit routes based on wind, time of day and so on. This proved to be even harder than finding the right trees. So, I did my best with what I know and have learned and found my entry/exits.
I continued scouting both on foot and on maps and aerial photos, made a few tweaks to a few spots and travel routes, and eagerly awaited the opener.
