Here is a good link
The only thing I disagree with in the link is that the law says it is illegal to store or posess, not to trasport a weapons. So if you have to drive on public roads from point A to B, not actually stop and walk around and posess the weapon you are okay. Otherwise youd have to contact the cheif of police for permission to drive through every town you traveled in.
I am thinking about sending a letter to Sheriff Zuruba and seeing if I get a responce because I live near a rather large unincorporated area.
