After getting all the supplies loaded into the biggest car that wasn't currently destroyed, he was ready to go. He decided to bring several guns and other weapons(Swords, knives), in case it went sour. He had, of course, taught the boys how to fire a gun before, but limited them to pistols at the firing range. Perhaps they would go hunting if they had time. When he was done, the boys were waiting. "Alright then, let's get going. Everything's ready." He gets in the drivers seat and waits for the boys, and when hey get in he starts driving.
(Make the trip last as long or as short as you want.)
