as the devils advocate, I have to say, harvest isn't a new age word in the hunting world, although I do agree that it is being used now days instead of kill, because it sounds better to the non-hunting world. just like if you said "i just harvested my neighbor, because he didn't return my shovel." It doesn't have the same effect, but even still, many popular hunters used it in years passed. fred bear can be heard using it in some of his videos.
I don't agree or disagree, if it's used or not, I don't care.. I personally use ''kill'' but these ''pro'' hunters nowdays are all about that $$$ and if using "harvest" keeps the attention of someone who may have been scared away by "kill" then they'll do it.
Yet in another light, some people use it as a sign of respect toward the animal they pursued, gettin' all spirtual about it and such, If thats your thing then cool. uncle ted does it, and he makes it seem like there is a true connection.
