Yellowdog the difference is in farmland/ flatland you may have two patches of cover separated by a 30yd wide shrubby creek bottom or fence row. You sit anywhere in that corridor and you will likely have deer in range, the deer have one option to travel between those patches of cover. In mountain ground say you have two patches of cover on top of a ridge. Yes the ridge top is the most defined travel pattern between the two, but deer likely have an option of a bench on either side of the ridge as well and they likely pick based on wind advantage. Now the deer have at minimum 3 options for travel. This is very simplified obviously, but for ease of hunting during the rut a well defined corridor in farmland is as predictable as it gets.
