I wish I had some sky to ground photos of some of my best pinch points to share and to help explain why and how these are pinch points and not just funnels. I consider a funnel a swath of land where deer are drawn to travel, were as a pinch point is a more specific point of travel " The hour glass effect if you will". These pinch points are a more narrowed spot of travel within a funnel. These " spots" are not always obvious by any means and can be right under your nose without realizing it. Pinch points can be used by deer some of the time or all of the time as deer pass threw a funnel depending on various factors, but the ones I'm interested in, are those used by mature bucks during the seek phase of the rut mainly. The best pinch points are the ones that restrict a deers travel the most of course, but those points are not always available. If you find one then you have the goose that laid the golden egg. Sometimes certain places draw deer travel for no obvious reason, although of course the deer know. I suspect it can be a combination of things, including of course air and/or wind currents for detection of threat or female. I'm sure others can add to this list, but Iv' rambled on enough for now.
