I just wrapped up my 3rd season of focusing on my place in PA. I feel like I have a pretty good handle on things there now, but another year and I will probably even have dates pinned on what does go into estrus and when. I've already got a few of them pegged, and seem to now know all the escape routes the deer used (both when being chased by bucks and people), the major buck bedding habitat, and the core areas the does use the most. I've also seemed to be able to focus on the most popular stream crossings as well. One more year and I think I'll really have it pegged.
