I was called to jury duty in Santa Monica back in the 90s during the second OJ Simpson trial. I would regularly see the media characters and lawyers from that trial in the elevator and also in the front lawn of the courthouse when they were being interviewed by reporters. One day, we were told we were dismissed from the jury pool and I had lunch across the street at a hotel dining room. I saw some of the journalists and lawyers from the trial.
After lunch, I ended up in a line of people near the exit and OJ was going down the line shaking hands and signing autographs, which at the time I thought was macabre. When he came face to face with me I didn't do anything, didn't shake hands or anything. He looked into my eyes briefly and looked away. I didn't have anything at all to say to him.
Had other sightings mostly in LA restaurants: Clyde Drexler, Terry Bradshaw, Gov Gray Davis, comedian Kevin Neelan, Valerie Harper, "Niles" from Frazier, Wolfgang Puck, Gary Busey, Harry Hamlin, Dennis Quaid and Ellen DeGeneres. Had an interesting encounter with Bill Cosby in SF in the 80s at a restaurant. Robert Mondavi, Tom Smothers and Pat Paulsen at a Wine Spectator tasting in SF in the 80s. And Franco Harris on a sidewalk in downtown SD prior to a Super Bowl in the early 00's.
As long as I'm being silly with all of this, I remember getting autographs from the Swingin' A's of the 70s - Reggie Jackson, Vida Blue, Joe Rudi, Gene Tenace, Sal Bando, Catfish Hunter, Bert Campaneris, etc. Of course, that program got thrown out by my Mom years ago.
