I agree with sheep and goats. I too have never hunted them,partly because of the stories I've heard from friends who have. It takes a lot of dedication(and sometimes money too) and often miles of climbing steep terrain and staulking. Then the reward for success is the even harder job of getting your animal back to where you started,over the same miles of tough terrain!
My hat is off to those who do it.
I voted sheep...getting a trophy old whitetail may be challenging, but getting "a deer" usually isn't. (Except this year, for me )
Same can be said of moose, bear and elk. Provided they're in your area in sufficient numbers they're not really all that bright. Sheep may not be all that bright either (I don't really know) - but getting up to them and staying up there long enough to get a shot, and then getting your trophy back down is pretty hard on the body.
You guys should come hunt rabbits at my house. The famer who owns the land planted "multi-floro Rose" years ago as a Gvt pgrm for "living hedgrows" It has since taken over and will cut you to threads. My buddie and me hunt bunnies after deer season is over and ice fishing has not yet begun. When we come in for lunch my wife just laughs at us, we are litterly covered with our own blood.
So I vote for the Cottentail Rabbit (with big pointy fangs. [anyone a Monty Python fan?])
As a Taxidermist I look at hundreds of Whitetail Bucks every year. I know that I have seen many different ways people judge the size of racks on live deer. I think for the most part they all are pretty close. I'm going to give you some measurements that I have noticed being right on in just about every deer. We have used it in the last couple years and have only been off by about 5-6 inches. We do study the deer while bowhunting so we get a little more time to look at them....
