[@Abefroeman] Hmm interesting concept, but I don't know if there really would have been any roads. We know there are some very limited ports and some crude forts, but no roads IIRC. And I think the Boars would work better as battle companions, not mounts. You'd have to come up with a good reason for the Night's Watch not to have sent a force since they raid beyond the wall, and it'd be pretty accessible to attack by a Night's Watch fleet.
