During an episode, Anna would drive over these grates on the road, known as a cattle guard or cattle grid. A cattle grid is a road obstacle made of parallel metal bars over a shallow pit that stops livestock from crossing while letting vehicles pass freely. Large four-legged animals will not walk over a cattle guard because they realize that their feet would slip and fall through the gaps between the metal slats, causing them to get stuck and/or injure themselves. The design of a "cattle guard" also allows for an opening to be left in a fence for vehicles to drive through freely without the need of a gate to open and close every time, while preventing animals from passing through. They are used to inhibit the passage of animals like horses, moose, deer, and cattle.
