The Amtrak's California Zephyr stop in Grand Junction, Utah is the only stop from San Francisco to Chicago in which anyone is able to exit the train and partake of local produce train-side.
I bought locally-grown grapes, carrots and apples.
You'd think Amtrak would twig that people stuck for two days on a train would be willing to spend $$ on fresh produce after having been subjected to microwave fries and "vegetarian entrees" - and would therefore have more of this sort of thing.
The mind boggles.
The grapes were fantastic.
