I used Code Blue, Doe Esterous for the frist time last weekend bow hunting in WI. I poured some on an atv trail and climed a tree 10 yards away, 20 minutes later I had a spike running down the trail, nose to the ground and grunting, he got to the sent and stoped on a dime. I now have a full freezer! (Mind over Matter) If you don’t mind, it don’t matter.
