Jeff, you've hunted that spot pretty hard over the last couple of years and really put some pressure on it this year with your mission to shoot does. IMO when you start killing deer on property it has a very adverse affect on future sightings. I feel this is for several reasons. First when you shoot a deer it causes a lot of noise and if there are other deer around they notice something just happened that wasn't good. Second, you have to track the deer that leaves your scent around and causes you to go in areas that you otherwise may not go. Third, you have to drag the deer out and that doubles the effects of tracking. So, while I agree that you probably should have been seeing some 1.5 olds running around it could be that deer are starting to avoid your area because of the pressure.

Fortunately for you, you acquired some new property to hunt so you can ease up the pressure on your regular spot and hopefully those sightings will start to increase again.
