Oh, for sure, I know you're using it to get in hunting. I have no issues with that at all. (Would probably try it myself sometime if I got the opportunity. Always wanted an excuse to get really good with .223.) But for some -- like a camping family with a naive pet toy poodle (read coyote snack) -- they might go elsewhere. And good point about dogs. So the response to sirens seems to be more a canid thing than a coyote thing. I'm still curious about why. What drove the evolution of that behavior?
