you get in and a marine leans over and shows you how to drive the thing and then you carefully drive it over the fort and a crowd of marines comes around and you and mr. holden sell their allotment of smokes and playboys and a few watches and a boom box and a lot of candy and then you get your m-16 and a map from the master sergeant with the camps marked out on it and you drive out of the fort into the afternoon sun and your last view of the fort is a marine with clippers shaving the heads of a long line of guys .
