Two things shocked him about his new home: the diversity of the people on the streets and the fantastic range of foods in the grocery stores. He took photographs of the rows and rows of sausages in Manhattan and mailed them to his mother in Moscow. "I'd never seen so many sausages," he says. But once he'd marveled at the American cornucopia, he stepped back from it all and wondered just how necessary all of this food was.

> In the end he became a finicky vegetarian."
