Hey Killer.
I've had great success with Code Blue doe in estrous in Illinois and Missouri. Had several bucks follow my drag right on in. Make sure to freshen your drag every hundred yards. One word of advice, don't open the bottle and leave it on the ground.When I first started using it I would leave the open bottle in a shooting lane but several bucks that trailed me up and smelled the bottle got squirrely when they got a real snootful. Must be too much of a good thing. Just leave your drag on a limb instead.
