I haven't used the growl (or ever heard a deer growl), but I ten dot agree about the deer here in VA. With no antler restrictions and two buck tags per yearI find about a9 to 1 doe to buck ratio (not counting button bucks), so the bucks aren't as aggressive towards each other as they are in many parts of the country. I think that's why I've never heard of rattling antlers working here in VA, either. So no growl for this bowhunter exceptmy growl of satisfaction at a good, clean hit with my arrow!
