Famous quotes containing the word march:
“On a late-winter evening in 1983, while driving through fog along the Maine coast, recollections of old campfires began to drift into the March mist, and I thought of the Abnaki Indians of the Algonquin tribe who dwelt near Bangor a thousand years ago.”
—Norman Mailer (b. 1923)
