Since by definition learning is change, when you learn nature's lessons, you are changed.

The scenery doesn't necessarily improve in proportion to how far you travel or how much you spend.

Parks benefit everyone. And those (men) who approach nature with arrogance instead of reverence may fail to reap the rewards available to all who recognize that the journeys are those made with the mind, not the body. 'When a mountain is climbed, it is said to be conquered--(may) as well say a man is conquered when a fly (lands) on his head.' -John Muir
