As Bob Vance (of Vance Refrigeration) and Phyllis drive off at the end of the episode you can see the shadow of a cameraman clearly visible on the side of the van that they are driving away in. You can see him follow the van as it drives away.
During Michael's talking head following the toast scene, a flyer is clearly visible behind him promoting Eastmont Community Center, in Los Angeles, CA, some 2000 miles from Scranton PA. The Community Center, is, however, just 20 miles by road from the filming location of the scene.
