Berkeley (city)
From Memory Alpha, the free Star Trek reference
Berkeley was a city on Earth, in the state of California, due east from San Francisco and north of Alameda. Home to the main campus of the University of California, Berkeley was headquarters to the Free Speech Movement of Earth's 1960s.
During a time-travel mission to 1986, James T. Kirk informed (not entirely truthfully) Dr. Gillian Taylor that Spock's aberrant behavior was result of his involvement with the Free Speech movement and his overindulgence in "LDS" [sic]. (Star Trek IV: The Voyage Home)
