bowmaker,
A landowner/tenant license restricts the person to his or her propery period. If off of their property they are no different than anyone else in that they would have to have a license in order to participate in the hunt. So, no, they could not help in the hunt on someone else's property irregardless of whether or not they were in possession of a weapon.
Scout,
I guess you lost me in your last post. I'm not sure if you're reading something into my post, or NWBuck's first one, or I wasn't clear enough in my original post.
If during the late muzzleloader season the only tag you have is the archery only tag, you can not have a muzzleloader in your possesion while deer hunting.
However, if you have your archery only tag and a late muzzleloader tag (either statewide or antlerless only) you can carry both your bow and muzzleloader since you have a license for both. That was NWBuck's question.
I hope this anwers your question.
