The following article can be found in many places on the internet.
"Another advantage that few people know about is using your fixed pins to make sure you clear brush or limbs. Put your 30-yard pin on the target and see where your 20-yard pin is. If it is on the limb you will hit it. If it is above or below the limb you will clear it."I know that I have read another article that expands on this principal and I have spent several days looking for it to no avail.

I am teaching my grandson to bow hunt and while the above article helps imensley, I would like to share the expanded version with him.
Does anyone here know where I can find the article?
