How does Cyrena arrange for Starla to travel alone by bus in the novel, Whistling Past the Graveyard?

An identity card is written out by Cyrena and pinned to Starla’s shirt. The identity card is a visual way for bus drivers and station workers to let Starla pass through unobstructed. The card contains an assumed name (Sarah Langsdon), the destination (Nashville/Lulu Langsdon), and Cyrena’s own number as the emergency number. Starla’s cover story is that her grandmother dropped her off at the station, and that she’ll be traveling alone. The paper will provide proof of this.
