RE: Funnel question?
Imagine, if the woods you hunted were shaped like an hourglass, that is big woods on one end, big woods on another end, and a thinner strip of woods inbetween with fields on each side. The place where the big woods narrows down to the thinner strip is called a "funnel" because the deer will want to travel back and forth between the woods without going into the fields during daylight hours. This causes them to "funnel" through that narrow strip.
Look at aireal photos of your hunting area and you may find a couple, just to note not all hunting areas have funnels that are as noticible as the one I explained.
