Watch ABC 7's report:
More than 3,000 people lined up Sunday morning to sign up for treatment at a massive free health clinic that will begin Tuesday at the Los Angeles Sports Arena.
Organizers of the free clinic, which served more than 6,300 people during its first visit to Los Angeles in August, have said those seeking help must pre-register Sunday, a change they hope will reduce waits and leave fewer people turned away.
Those at the front of the line had packed duffel bags and folding chairs to wait overnight in brisk temperatures.
