Famous quotes containing the word roads:
“Lift your eyes
Where the roads dip and where the roads rise
Seek only there
Where the grey light meets the green air
The hermit’s chapel, the pilgrim’s prayer.”
—T.S. (Thomas Stearns)
“This, my first [bicycle] had an intrinsic beauty. And it opened for me an era of all but flying, which roads emptily crossing the airy, gold-gorsy Common enhanced. Nothing since has equalled that birdlike freedom.”
—Elizabeth Bowen (1899–1973)
“Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could”
—Robert Frost (1874–1963)
