DO NOT...I REPEAT... DO NOT thin out your property. Additionally, 5 guys on 100 acres even if you only have 10 stands is overload for a property. Stay realistic. You are not going to turn 130" deer in to 150" deer. Age, genetics and nutrition (in that order) are what impact the size of a buck's antlers, and generally speaking, the overall size/health of a deer period. I manage 80 acres with an additional 50 acre and 320 acre property in what's become a de-facto deer management co-op. We've seen the biggest impact by not shooting does and letting all the thick areas get thicker, and letting other areas grow up. We are getting more older age class deer total and therefore, more and bigger bucks. In 10 years of managing the local deer herd, nothing has helped more than adding bedding areas, creating sanctuaries and learning to lay off the does. We've never harvested small bucks and in the 10 years, I can't say that we've definitively added X-number of inches to our bucks. We have more mature deer overall, which has created better hunting opportunities for trophy class animals. I suggest some well placed, small, food plots to hunt over. Additionally, start a mineral site. View this thread for more details on mineral sites:

My honest opinion is that you need less stands, better access and a clearly defined set of management principles before you get too deep in to it. Nothing is more frustrating than putting time, money, energy in to a property and someone comes along and backtracks your progress.
