And DMC, don't worry, there are a LOT of deer in the triangle area. Urban sprawl and development have created a near-unending supply of the edge habitat they love. I'm not sure where you got your 2/3 herd reduction number, but it is certainly not the case. Most deer mortality comes from vehicle encounters, starvation, and stray or unsupervised dogs, particularly when the latter pack up. You may also be seeing the work of coy-dogs -- these hybrids are more aggressive and visible than their wild predecessors.
If you'd like some more accurate deer numbers for the area, I can go down the hall for you (I focus on the fish so don't have the numbers at the top of my head). Domestic pets and other small animals should always be contained and/or supervised outdoors, cats should be kept indoors not only for their own safety but to prevent their wildlife serial killer habits (I love my INDOOR cats), and donkeys are indeed excellent guardians, as are llamas or a particularly cranky horse.
