I'm with jimbob86. Bring enough gun and put the bullet where it counts (heart/lungs). You might or might not knock em down right there, but they won't go far. At the risk of starting a verbal fight, I've never given much credence to the folks that talk about neck shots and ear shots and what have you. Under ideal conditions, yes you can take that shot, but I've shot a lot of deer over more than a couple of decades and I have rarely chosen the neck shot. Just pop em behind the shoulder, waste no meat, go get the ATV and tell momma to heat up the skillet.
I never ran into this neck shooting mania till I moved to Texas. I am a firm believer that the neck shooters don't have as much meat in the freezer. There...I've said it! Sooner or later I knew it'd have to come out.
