You can find all of the supplies you want for the road, since this is more or less a fort. Plenty of supplies are carted in from the south, to make sure that this place does not fall to the hoards from the north. Plenty of capital going into expanding into the north, and that requires food and man power.<br/><br/>You can take as long as you feel like it is needed to get all of the basic food and clothes and cookware you will need for the trip.
