Maybe she thought that if she planted a piece of the horn somewhere in the wilds, a new moose would grow to replace the one she "harvested."

Funny.
I'm lucky to live in a place wherealmost everybody I know hunts. I think the internet is just about the only place I've heard the term "harvest" used in relation to hunting, although looking in the Oregon Game Regs just now, that's the term used there, too. Huh.
Oh, well. Whether we kill, shoot, slay or harvest, the more people who hunt, the better.
