ALPINE, Calif. — (AP) — One of California’s largest tribal casinos reopened Monday to a large crowd as customers who had their temperatures taken at the door and were ordered to wear facial coverings.

The Viejas Casino & Resort in Alpine was the first of three big casinos in the San Diego area to open this week. The opening comes amid concerns from some public health officials who acknowledged tribes are sovereign authorities and not subject to state and local restrictions.

Within an hour of opening at 8 a.m., the first three floors of four-story parking garage were full.
