Note, by the way, that San Vicente Mountain Park was where the missile guidance radars were located, but the missiles themselves were stationed (and would have launched from) the Sepulveda Basin, near what is now the California Air National Guard facility just off Victory Boulevard. It hosted both Nike-Ajax conventional missiles, and the later Nike-Hercules nuclear-tipped missiles.
(And the site's designation was LA96C, "Los Angeles site 96 Control." The LA98 Control site was atop Magic Mountain, a peak in the San Gabriel Mountains. Its Launch & Admin facility was in Soledad Canyon near Lang Station.
