Not something I've ever been particularly interested in, but Kansas just legalized coyote hunting at night under lights or with night vision scopes (I need to look into it in more detail about exactly what is allowed). I'm generally of the opinion that killing coyotes is a good thing and it would seem to be a lot easier at night. Getting serious about hunting them has been something I've been meaning to do for a while.
Again, I have effectively zero knowlege about such things. Has technology driven the prices down on these nowadays? Will it wash out under the muzzle flash of a rifle firing? How do you zero one? Does it require a shooting range at night?
