I have a theory on WHY WE KEEP HITTING DEER. We don't hit squirrels and dogs and whatever else as much as we hit deer; where I live, anyway. You might say that's only because we squirrels are small and don't dent our cars. Well, there would be a lot more dead squirrels spattering the roads if we hit squirrels as much as we hit deer. This is my theory: DEER ARE SUICIDE 'BOMBERS'. Screw the Middle East! It's deer we need to worry about. Notice how they wait in the ditch, right where you can't see them, especially at night, which is exactly when deer come out. Then right as you're driving by, BOOM. And endless swearing from the whoever is driving. Either that, or they're just the stupidest animals alive.
Obviously the first suggestion is the most likely :P
