The Simpsons at FOX Studios.


The billboards celebrating 300 episodes at the studio's main entrance on Pico Boulevard.

A closer view of the billboard, unfortunately OFF is obscured by the traffic light.

The show's soundstage, which is also used by The WB's "Reba."

An inflatable near the visitor's parking lot B.
I was at the FOX lot to visit the set of NYPD Blue and you can view those pictures here, unfortunately I've never heard from anyone at The Simpsons so I couldn't get any closer than outside the soundstage.
