When California was anticipating a spring surge in coronavirus cases it turned an old NBA arena and practice facility into a field hospital prepared to take hundreds of patients. They were told to expect 30 to 60 patients within the first few days, but only nine arrived over the next 10 weeks. (AP Photo/Rich Pedroncelli, File)
