Here is a good funnel/pinch point to hunt during the rut.
Red: Treestand
Yellow: Bedding areas
Light Blue: Deer trail
Light Brown: Thick brush/fallen trees
My stand is located just south of a large food plot and is overlooking a pinch point in a "deep cut."
A deep cut is a terrain feature found between two points and is usually pretty eroded due to heavy amounts of rain. Cuts often contain large rocks, heavy brush, and/or fallen trees. As a result, deer are often limited to one or two trails. In my example, the only feasible way around the cut is an old logging road. As such, all the trails funnel into one trail at the cut.
Most importantly, the cut is located between two bedding areas. So when bucks start cruising these bedding areas, the cut will funnel them right by my stand.
I'll hunt this stand with a North/Northeast wind coming from behind me and blowing over the top of the area I'm watching. The bucks will travel this trail using a north wind b/c they will be able to take advantage of the wind tunnel (prevailing wind meeting rising thermals). By staying in the wind tunnel, the bucks can smell any estrous does above them and below them. If the wind was out of the south, the bucks could only smell does bedded below them.
