I dunno.  I miss the old days when you could use anything other than a .22 rimfire anywhere in the state, and even that restriction was lifted north of the Yukon.  Shucks, if you wanted to drop out of a tree on a moose and kill him with your bare hands that was okay, as long as it was during open season...  But then again we had half the people we have now. :cry: 
I really don't see how an ATV will help on a muzzleloader hunt, but then I never had much use for one anyway.  What experience I've had with folks on snow goes have left kind of a sour taste in my mouth for using motorized vehicles in hunting.
