It’s nearly 12:30 p.m. when a rushed young man drops by the Chicago Recovery Alliance’s parked silver truck in West Garfield Park. He’s turned away for HIV testing, but told to come back next week, but just a bit earlier. The truck can’t be late for its next stop in Austin. If the staff and volunteers don’t show up, addicts might think the program, like others facing budget shortfalls, is unreliable. And that means next time they need clean syringes, they might not come back to the truck.
