Quote of the Month

Not until the afternoon does the wind begin to blow, raising dust and sand in funnel-shaped twisters that spin across the desert briefly, like dancers, and then collapse — whirlwinds from which issue no voices or word except the forlorn moan of the elements under stress.
— Edward Abbey, Desert Solitaire
