Deer & animal avoidance systems
Our local Utah/Wyoming mountains have a lot of wild life (elk, deer, etc.), plus a good bit of free range livestock (cows, sheep). Never drive at dusk/night because of this, but the free range animals frequently trespass on the roads even in daylight, while the wildlife is drawn to same once the mountain shadows cover the road as early as 3 pm in some areas. Plus there are those occasional misplanned trips where I find myself miles from home with dusk/night approaching.
Does anybody have any experience with the deer/animal avoidance systems on the market? I know Hornet makes an electrical system that emits a high pitch sound to scare the animals away, and I've seen others that work simply with airflow. Does anyone know if any of these systems are effective or know of another type that is.
