The best funnel I've found this season has been in a creek drainage that's a little over 100 yards wide, situated between two bean fields. This area was timbered a decade or so ago, and so the understory is thick. But the terrain is rolling hills, and when combined with the thick stuff and the meandering creek beds, there are bound to be a few funnels. The one I've found is a saddle between two ridges, bisected by a creek arm. One side of the creek is a high bank with little understory; the other side is low and thick. While scouting, I naturally followed the high bank myself because that's where the walking was easiest. It was apparent from all the tracks and rubs that deer passing from one bean field to the other had been doing the same.
