up truck with some  Navajo Indians, one of whom introduces himself in Navajo language.  However, if you look closely at an earlier scene at the 27:30 mark,  we see them getting out of the same truck with the same Indians.  There is a continuity error here because the kids had parted ways  with the truck after the first scene and got a ride with a biker  gang. The two aforementioned scenes were obviously shot together and  the editors overlooked or ignored this continuity problem.
