One day's exposure to mountains is better than cartloads of books. See how willingly Nature poses herself upon photographers' plates. No earthly chemicals are so sensitive as those of the human soul.
John MuirIf I should be fated to walk no more with Nature, be compelled to leave all I most devoutly love in the wilderness, return to civilization and be twisted into the characterless cable of society, then these sweet, free, cumberless rovings will be as chinks and slits on life's horizon, through which I may obtain glimpses of the treasures that lie in God's wilds beyond my reach.
