Dang, you are super lucky. Here in the SW corner of colorado, hitting a deer or seeing a dead one on the side of the road is a daily occurance. I have managed to hit two now in my many years driving the 70 miles to work. One in a ranger, only broke the grill, and one in my old dodge ram with a "deer slayer" bumper. Needless to say, the dodge was fine, and no damage, well worth the 1K for the bumper. After selling that truck, kept the bumper and gave it to my dad for his dodge, and he has hit one with it, and still no damage. Now as to the deer whistles, my grandfather, god bless, has hit more deer with his wagon when i was driving than I ever did hunting, and I normally brought one home a year. I avoid the whistles, as everyone I see here, hits deer with them. The PD put them on half of their fleet and the half that had them, almost all of them hit a deer at some point. The other half, i think only one hit one, and he was following one of the pd cars that had whistles on it. Just my 2 and 1/2 cents
