- Gabby: You two ought to get along just like that span of mules over there. They've been wearing the same harness for eleven years.
- [first title card]
- Title Card: In the early days when California was first admitted to the Union, a rush of covered wagons, bringing land-hungry settlers, fortune hunters and outlaws, threatened the very existence of the old Spanish Dons and their vast ranchos.
- [first lines]
- Don José Vargas: Here they come, these Americanos and their covered wagons. Pedro, the days of the Dons are numbered.
- Pedro: And why do you say that Mr. Don.
- Don José Vargas: Too much money is made out of people soft. Our days, our siestas, our night fiestas, they are no match to these lean, hungry gringos. What they want - they take! And soon they will have all of our California.
- Jean: I suppose you're going to see that young man that you've been bragging about ever since we left?
- Gabby: Well, why shouldn't I brag about Roy Rogers? I brung him out here in '46...
- Gabby, Jean: And I learned him everything he knows.
- Gabby: Well, I did. Now, he's the top rider of the whole durn hacienda.
- Roy Rogers: [singing] Side by side, Let us ride, 'Neath the skyline, Let the sun fill our songs full of laughter...
- Roy Rogers: Gabby, you old porch swing!
- Gabby: Why, you young maverick. You've sprouted like a toad stool.
- Roy Rogers: You're just as ornery as ever.
- Roy Rogers: What are you doin' in California, Gabby?
- Gabby: Oh, fetchin' out another herd of greenhorns in their covered wagons.
- Roy Rogers: California isn't such a bad place, once you get used to it.
- Jean: It is peaceful. Listen to those waves. Kinda makes you sleepy, doesn't it?
- Roy Rogers: What about those stars?
- [rumbling]
- Jean: What's that?
- Roy Rogers: Oh, it's just an earthquake.
- Rita Vargas: Has my father lost his heart for the poor and unfortunate? She's in great trouble. For me, father?
- Don José Vargas: If you can only handle a husband as cleverly as you do your old father. Allright, I will see her.
- Don José Vargas: Can't we even have our fandango without these Americanos thrusting themselves upon us?
- Don José Vargas: Something must be done to stop these ruthless gringos before they drive us out of California.
