Let me relay an anecdote that will frame my perspective on this...
My dad bought 96 acres in 2005. I was 23 making great money, no wife or kids. I was ATE up with the Drurys and thought I'd be the Mark Drury of Washington County. Sad, I know. I lunged in to projects that I am still regretting and missed the boat on projects I should have done LONG before I dicked around with some of the stuff I wasted time, money and energy on. Dad sold 16 acres shortly after he bought the farm and now 12 years later, I am just hitting my stride from a habitat management standpoint on the 80 acres that's left. The hunting will change as habitat and neighbors change. Be adaptable and be willing to think outside the box. Don't just plan based on your 105. Consider the entire 640-acre square mile around your 105 because that entire area, and more, will influence what you should be doing on your 105. I can only manage 80 acres, but I can do so with the other 560 acres in mind.
I would not do a damn thing out there other than observe, hunt, and scout until March 1, 2018. Then, and only then, would I get to work. This is 35 year old me talking to 23 year old me...
