The drill is simple but tedious. Starting on the farthest downwind end of the field, stick your noggin into the first row of corn. Scan left, then right (or vice versa), and search for a bedded or feeding whitetail. Assuming you don’t see a buck in the first row, you step into that row, then repeat the process until you emerge on the other end. Move down about 30 yards, and repeat the process, crossing the rows in the other direction. Repeat until you’ve covered the field.
