Famous quotes containing the word swamp:
“When I would recreate myself, I seek the darkest wood, the thickest and most interminable and, to the citizen, most dismal, swamp. I enter a swamp as a sacred place, a sanctum sanctorum. There is the strength, the marrow, of Nature.”
—Henry David Thoreau (1817–1862)
