Spike buck,
I have a few pointers that might help on decoying deer. First of all i would put the decoy about 20 - 25 yards upwind of you, 9 times out of 10 the deer coming in will get downwind of your decoy, then this would give you an easy 10 - 15 yard shot. Secondly i would shy away from putting scent directly on the decoy rather spraying some scent around the decoy, or getting some of those 35mm film canisters and putting a cotton ball inside with some scent on it underneath of your decoy. And as bobcat said make sure you spray your hands and decoy down with some scent elimination spray before and after you handle it. Another thing i have found that if you don' t put any scent on your decoy and keep it scent free you can hide the decoy in some bushes around your stand so you don' t have to carry it out there every time. I have always used a buck decoy, but if you are going after a fork horn i would have to agree with bobcat and use a doe, any buck decoy any more has a descent sized rack on it and might do more harm than good on a fork horn. Hope all of this helps, it has worked good for me in the past. Good luck on getting your buck.
