RE: cover sent that works?
This is the way I look at cover-up scents...
A hound dog can follow a 2-3 day old trail. A deer's nose is probably as good if not better since its front end saves its rear end. Now... the human nose sucks rear end in comparison but do you think that with your eyes closed andusing just your nose, you can tell the difference between the pumpkin pie and the rump roast if the two were set side by side on the dinner table? Of course right?
My point is, cover-up only means there are now 2 scents. So instead of thinking "there's a guy over there", the deer's thinking "hold on, there's a guy over there with a (trained to kill) pet racoon that he intends to unleash on me. Hmmm... better turn around."
