What I call pinch points are just about the same thing as a funnel. Say you got big block of woods 300 yards across on one side is a river or creek on the other is a big field. What I look for around wheeler is a place where the creek cuts into the woods closing the gap between the field and it. Even better is when a beaver has a small creek dammed up creating a long 2 to 3 foot deep pond in the woods running between the field and river. This creates a choking point that deer will travel through and allow you to have a good chance at not only seeing deer but getting a shot on one. Don't get me wrong them deer aren't afraid of the water they will cross it any time but I found that cruising bucks will hug the water line looking for doe's that have passed through. And the doe's follow the water line's eating left over acorns and seeds that are on the waters edge or floating just off the bank. I don't know if I explained it that well but I tried. Good hunting.
