Locations - airfield scene
Okay, I have conflicting information re. the airfield/junkyard scene at the end of the movie. One source says this was filmed at the airport south of Fernley, NV. I've been there and it looks right (no junkyard there now). In the movie, on a hill in the background you can see an advertisement for Harvey's Inn carved into the dirt. That's not to be seen at Fernley now.
In the IMDb locations notes on this site, it says that this scene was filmed at a junkyard in Mustang, NV but I don't think the terrain is right for this to be true.
