It's shown up pretty close to where I hunt in PA and from my understanding they have some "sharpshooters" in that area this winter shooting deer.
I don't know if that's for testing purposes or to reduce the deer numbers.
I think there's just a big gap in what the smart people know about this and what they don't. All of the info that you see is that it's terrible for deer, but shouldn't bother humans. But occasionally an article pops up, like what I linked to, that says not so fast, it might be bad news for humans.
