While on my way to the Hollywood Farmer's Market, I chanced by El Centro Avenue north of Sunset Blvd. A number of props were parked on the street. Viz.:

The building in the background is the former CBS Headquarters.

Electric Generator, not a "prop".

Production Vehicles, also not "props".

Cast Trailers or Dressing Rooms
