Good insights everyone,I agree with not shooting if one is on high alert because you may not only miss but only wound the animal as well. Distance is an issue when it's dead quite in the woods and every sound is magnified 10 fold. 20 yards or less is a good limit in my opinion for taking a shot in these situations. A quite,faster bow sure can't hurt ones chances either when they are a little edgie. A good angle and a lower aim should help as well,a bad angle shrinks you kill zone. Good Hunting and stay after them you will nail one sooner or later.
