The Big Sombrero (1949)
Estrellita Estrada: And all that you see is Estrada land - the Big Sombrero.
Gene Autry: Where's the end of it?
Estrellita Estrada: Oh, it's not in sight. There's a saying of my people that when you can look to the four corners and see only your own land, then you can truthfully say, "I have a rancho."
