If you mean the rifle I'd try the local sporting goods/gun shop.
If you talking about a mean bear hunter, I'm pretty sure slavery has been outlawed but you might be able to rent one. I understand some of the bear guides in both Alaska and Maine can get pretty frosty!
Want a quick and inexpensive call for Moose? Take an empty 32 ounce coffee can, and make a small slit in the bottom, only about a quarter inch. Then, take one of those really big red rubber bands, the ones that go around big folders. Cut the rubber band to make one long piece.
Now, thread one end of the band and tie a knot on the outside of the can so it won't pull through. Cut the band off on the other side so it is even with the top of the can.
Now, wet your finger,...
