Having just hunted deer in Idaho for the first time last year, my personal opinion about them isn't fully formed yet. BUT, it was raised a few hackles when, after helping a local load a nice whitetail into his truck, the conversation turned to the wolves and grizzlies in the Panhandle. That local hunter said the grizzlies aren't a real problem unless you surprise one, otherwise just give it room. The wolves, on the other hand "them bastards will circle ya..be careful."
Living on the Wa. coast, I'm not crazy about an introduction here, either. Between the cougars, indians, and illegal alien poachers, the deer populations here are not what they were.
