which are filled to capacity. The irregular shapes remind you of all the effort that's gone

in to getting ready for the journey ahead. They and you are well prepared to begin your hike

along the 6-foot track, a trail that will lead you through the blue mountains of New South Wales,

Australia. Two days from now, you'll arrive at the marvellous

and mysterious Genolan caves. Hidden within the extensive cave network are abandoned mines,

colorful lights that dance on the walls, and tiny passages that twist and turn like an unraveling

string. Along the way, you plan to camp at two lovely and remote sites, nothing more than

isolated clearings that will allow you some space for your thoughts.

flash of lightning some years ago.

You're grateful for the pleasant weather now. The wind nuzzles your cheeks gently,

as the sun splashes warmth over your nose. You've decided to head out in the early afternoon,
