Book excerpt: Mark Singer's lively and extremely popular "U.S. Journal" column in The New Yorker featured under-the-radar stories that were unusual but emblematic tales of American life. A first-time collection of these pieces, Somewhere in America offers an illuminating glimpse of the cultural kaleidoscope of our country. From worm farmers in Weleetka, Oklahoma, to angry nudists in Wilmington, Vermont, Singer proves that "sometimes you don't even need a passport to experience a new nation" (U.S. News & World Report).
