RE: Funnel question?
Funnel can also mean if your land has a large hill AKA ridge on it. There are ussaly spots where the land will sort of dip or meet with another hill and turn. This creates a funnel that water comes off the hill in when it rains hard. That is the easiest way to find them. Deer will use this path to move from one hill to another without walking out into a feld or just before they cross a field so they can check it out first.
