i walked on , part of a broad wash of people heading across the concourse to the doors , some men and women in uniform , either class as like my own or the old woodland-pattern bdus we had back then , and some men and women obviously military but out of uniform , in suits or work clothes , and some obvious civilians , some of each category carrying bags or briefcases or packages , all of each category slowing and sidestepping and shuffling as the broad wash of people narrowed to a tight arrowhead and then narrowed further still to lonely single file or collegial two-by-two , as folks got ready to stream inside .
