Famous quotes containing the word car:
“Raising children is a spur-of-the-moment, seat-of-the-pants sort of deal, as any parent knows, particularly after an adult child says that his most searing memory consists of an offhand comment in the car on the way to second grade that the parent cannot even dimly recall.”
—Anna Quindlen (b. 1952)
“It all began so beautifully. After a drizzle in the morning, the sun came out bright and clear. We were driving into Dallas. In the lead car were President and Mrs. Kennedy.”
—Lady Bird Johnson (b. 1912)
