I'M RIDING ALONG with Tristessa in the cab, drunk, with big bottle of Juarez Bourbon whiskey in the till-bag railroad lootbag they'd accused me of holding in railroad 1952-here I am in Mexico City, rainy Saturday night, mysteries, old dream sidestreets with no names reeling in, the little street where I'd walked through crowds of gloomy Hobo Indians wrapped in tragic shawls enough to make you cry and you thought you saw knives flashing beneath the folds-lugubrious dreams as tragic as the one of Old Railroad Night where my father sits big of thighs in smoking car of night, outside's a brakeman with red light and white light, lumbering in the sad vast mist tracks of life-but now I'm up on that Vegetable plateau Mexico, the moon of Citlapol a few nights earlier I'd stumbled to on the sleepy roof on the way to the ancient dripping stone toilet-Tristessa is high, beautiful as ever, goin home gayly to go to bed and enjoy her morphine.
