Southeast Region - Buck Hill Area. You can choose either Whitetail Deer Hunt.
As soon as you start the map, proceed forward on the path to the top of the hill. There will be 5 whitetail deer. 3 Males and 2 Females. If they are not there, simply restart the map. Now using LB (Binoculars) tag the 8+point Male Buck (every time I've played there has been one with 7 Left and 7 Right, 1 right and 4 left, and 2 and 3). Now keep switching tags between 8+point buck and other males, back and forth until you tag the 8+point buck 15 times.
