SAN FRANCISCO (KGO) -- Full moons won't be the same at the San Francisco Zoo.
ABC7 News was at the zoo as a mariachi band celebrated the opening of a new wolf exhibit.
Three Mexican gray wolves will live there. The exhibit has automatic feeders and surveillance cameras to keep human contact to a minimum.
The Mexican gray wolf is endangered. Only 100 exist in the wild.
These three wolf brothers will be used in a breeding program.
