RE: How can I increase chances of getting a buck
Find the bedding area used by the Doe's, but DO NOT enter them, hunt on the edges, or find the travel route which they take to and from, and ambush them. This is the time of year the bucks will be cruising the bedding areas in search of those first Doe's that come into estrus.
Another option is find the evening food source (corn or bean field perhaps), chances are you'd get busted trying to sneak in there before first light, so plan on only hunting that in theevening, but give yourself plenty of time to get set-up and settled in, you don't want to be rushed.
