They left the van parked there, and walked back along the Embarcadero, past razor wire and barricades that sealed (ineffectually, Chevette knew) the ruined piers. There were dealers in the shadows there, and before they'd gotten to the bridge they were offered speed, plug, weed, opium, and dancer. Chevette explained that these dealers weren't sufficiently competitive to take and hold positions farther along, nearer the bridge. Those were the coveted spots, and the dealers along the Embarcadero were either moving toward or away from that particular arena.
