I grew up learning to hunt in CO. Glassing, spot and stalk and still hunting were what we used. Deer drives simply aren't done out there. I have nothing against them but in my mind the shooter needs to be very careful about what shot they take and what shot they pass on. And I'm betting that most deer taken on drives are dropped with chest shots, not neck or head shots. There is a reason, bigger target. Doesn't matter if a deer is standing still or moving, the chest will always be a bigger target. It is what it is.
