Many of us commute to our ponds from the city and often that commute takes us through deer country. With two damaged areas on my truck and another near miss last week, I searched for some help...ran across the Deer Alerts that can be mounted on your vehicle. They supposedly send out a warning at a frequency we can't hear, but deer can and then avoid your vehicle.

Anyone have experiences with these products and do they work?....or do they scare all the cows away in all the road-side pastures?
