Assuming the man in Dr. Bob Niedorf's (Brent Spiner's) question is from California, then the question is answered at 12:12 p.m. on July 26, 1996.
Old town Auburn, California was used for the scenes in town. Most of the businesses are still in operation, and thrive off of the tourism generated by the movie to this day. Auburn is also the birthplace of Kane Hodder who played Jason Voorhees in the Friday the 13th movies.
The main part of the movie was filmed in Old Town, Auburn, California. The gas station was fake, and built in front of the U.S. Post Office in town. The bar scenes were filmed in the old Shanghai, which is now Auburn Ale House. Doc Brunder (Robert Duvall) mooned George Malley (John Travolta) from the window of then, TSUDA's store. It is now Sierra Moon Goldsmith.
