I am planning on moving from Alaska to North Carolina and would like to drive down. What documents do I need (other than a passport) to get across the borders? Do I need to declare everything I have in my trailer? And also, is a rabies certificate all I need for my two dogs? Do they need to be kenneled or can they just be in the back seat? I won’t have any firearms (I don’t own any) I’ve read that they cause problems at the border though, is there any other items that will cause problems for me? Any information would be great!
