I can attest that calling (grunts and bleats) work fanatastically in PA. Rattling on the other hand, not so much, yes at times but I agree to the statement that you will spook more deer than rattle in.

I will say however that I don't sit in my stand and randomly call all day. A few grunts or bleats now and again but very seldom. I usually call only when I see a deer and can watch it's reaction. I've personally never seen a negative reaction to grunting and bleating. There is usually a positive response or no response what so ever.

But when it does work, it's like bringing them in on a fishing line.
