Decoying antelope in archery season is a great way to hunt them. Some folks will tell you they get several bucks a day charging in on them, while others, like myself, seem to chase them off with a deke. I haven't mastered that project yet, but I do know that using an antelope call in conjunction with the decoy works well. I think thethree most critical aspects are:

1. Setting up so as not to alert them scent/sight.
2. Make sure you are hitting the rut in the peak (mid to late August here)
3. Hunt an area that is archery only, or gets limited pressure during rifle.
