chapter twenty-five and the three of you drive out of town and out on the highway and through the checkpoint and then on to the highway and you stomp on the gas and the humvee spins up to about fifty , which is really hauling for them , and finally mr. holden leans over and says slow down petty officer and you take your foot off the gas and the humvee winds down and then you put the thing in neutral and just let it glide for about a half mile and then when its going about a mile per hour you pull over to the side and turn it off and you sit there with the engine creaking and a little wind in your ears , and then you lean over the side of the humvee and puke in the dirt .
