"To appreciate the wild and sharp flavors of these October fruits, it is necessary that you be breathing the sharp October or November air. The out-door air and exercise which the walker gets give a different tone to his palate, and he craves a fruit which the sedentary would call harsh and crabbed. They must be eaten in the fields, when your system is all aglow with exercise, when the frosty weather nips your fingers, the wind rattles the bare boughs or rustles the few remaining leaves, and the jay is heard screaming around. What is sour in the house a bracing walk makes sweet. Some of these apples might be labelled, 'To be eaten in the wind.'" - 'Wild Apples', Henry David Thoreau.
