|Scalia at Pepperdine in 2009|
In recent years, Justice Scalia visited Pepperdine Law School, USC, USD, and appeared in California Lawyer (video) and at the State Bar's Annual Meeting in San Diego in 2014. He also attended bar events in LA (particularly along with his co-author Bryan Garner, e.g., here for ABTL). Considering how infrequently SCOTUS Justices visit SoCal, Justice Scalia was arguably something of a regular.
