That one measley Walden Pond picture just wasn't enough. How about a little more Thoreau goodness?
"I would rather sit in the open air, for no dust gathers on the grass..."
"Be rather the Mungo Park, the Lewis and Clarke and Frobisher, of your own streams and oceans; explore your own higher latitudes...Nay, be a Columbus to whole new continents and worlds within you, opening new channels, not of trade, but of thought."
"...beware of all enterprises that require new clothes, and not rather a new wearer of clothes."
"Books are the treasured wealth of the world and the fit inheritance of generations and nations."
And my favorite:
"Only that day dawns to which we are awake."
Am I awake? Are you?
