In Chapter 4 of On The Road, Dean says to Sal:
"Oh! This is too great to be true. Gurls, gurls. And particularly right now in my stage and condition, Sal, I am digging the interiors of these homes as we pass them — these gone doorways and you look inside and see beds of straw and little brown kids sleeping and stirring to wake, their thoughts congealing from the empty mind of sleep, their selves rising, and the mothers cooking up breakfast in iron pots, and dig them shutters they have for windows and the old men, the old men are so cool and grand not bothered by anything. There’s no suspicion here, nothing like that. Everybody’s cool, everybody looks at you with such straight brown eyes and they don’t say anything, just look, and in that look all the human qualities are soft and subdued and still there. Dig all the foolish stories you read about Mexico and the sleeping gringo and all that crap — and crap about greasers and so on — and all it is, people here are straight and kind and don’t put down any bull. I’m so amazed by this."
All of that was just from passing through houses on the road. This is an example of how detailed Kerouac's writing is.
