How to Measure Distances in the Dark

The phenomenon that Jason refers to is known as eye shine. You see it for example with cats and dogs when their eyes seem to glow in the dark. A challenge for the Bigfoot explanation would be why the creature's eyes seemed low to the road and then shot up to the height of a man or taller. Horses are herbivores or plant eaters whose survival strategy is running away from things. As a result they have eyes that are primarily side mounted. Whereas animals that hunt including carnivores like wolves, big cats and birds of prey need front mounted eyes so they can better lock in on what they're looking at.
