Where I hunt, you are are not consistently stalking to within 200 yards let alone 100. These deer are very highly pressured, and rarely stay in a field for more than a minute if they even stay for more than 10 seconds. If you aren't already on the ground, then by the time you could walk 100 yards closer the deer will be gone, even without getting spooked, just because these deer never stop moving. I'm not saying they are hard to hunt, but they are very difficult to stalk to within close range. I have killed them with a bow many times, and will continue to do so, but I've also had seasons where I never got a chance at any deer within bow range.
