I hit one in my parent's Intrepid a few years back doing about 80mph on the interstate. I was going fast enough that the impact didnt really move the car at all but it absolutely obliterated the right front of the car, headlight gone, tore off half the bumper cover, dented the fender and hood badly. Ended up doing about $5000 worth of damage and USAA just totalled the car. Scared the living crap out of me too. It has made me hate driving at night because Alabama seems to be dear heaven. I drive from Auburn to Birmingham quite regularly at night and last time I did I counted 57 dear grazing on the side of the road on about a 45 mile stretch of US280.
