Famous quotes containing the words cross and/or section:

& cross the damp cold lawn & down the bluff
into the terrible water & walk forever
under it out toward the island.”
—John Berryman (1914–1972)
“The demonstrations are always early in the morning, at six o’clock. It’s wonderful, because I’m not doing anything at six anyway, so why not demonstrate?... When you’ve written to your president, to your congressman, to your senator and nothing, nothing has come of it, you take to the streets.”
—Erica Bouza, U.S. jewelry designer and social activist. As quoted in The Great Divide, book 2, section 7, by Studs Terkel (1988)
