Well, from my limited experience and the guidance of several cranky old men, if you have the means and stamina. The best way is to scout out your buck, bring a sleeping bag and put em' to bed and shoot em' at first light. Antelope are diurnal and won't go anywhere during the night unless pushed hard by yotes'. If you camp on thier bedding site and sneak to within rifle range before daybreak, you should get a shot at first legal shooting light.
Do we screen for all the loud snoring hunters I have heard in hunting camp through the years? What about all those dessert rattlers? Your right if you don't snore to loud and don't mind a rattler snugling up to you on the cool dessert nights. I took a realy nice buck off a waterhole one time by spending the night in my blind. He watered early and no way to ambush him without spending the night in there. Just never heard of anyone else doing that. You have a very good point for people dedicated to getting a particular animal.
Predictions are difficult, especially when they involve the future
