Even with orange requirements 1-3 hunters are unfortunately shot and killed every year in Minnesota, almost always during deer hunting season. I'm not sure what these figures are for the entire US. One thing is certain, the numbers would be much higher without the orange. I gave up bird hunting during deer season, just too dangerous. As far as education is concerned, a few dogs, cows and horses are also shot. You'd think somewhere along the line people would learn what a deer looks like.
