RE: calling for deer
Go to a sporting goods store or a video store and rent a video or two on calls and calling. You will learn a lot more from them than you will here.
I never leave home without a couple deer calls and always keep one handy. To actually use them to attract unseen deer to me, I use them in combo with rattling. But if I spook a deer or see a deer I am not likely to get a shot at, I use a call to calm the deer and sometimes bring them in closer for a shot. I have shot at deer and missed and called to stop them for another chance.
