Hiking.

Hiking is probably one of my favorite things to do here.
Vigorous exercise combined with exploration.
The satisfying feeling of complete exhaustion upon return home following an intrepid adventure.
A cleansing effect.
A feat accomplished.
No technology, social convention or presumed identity.
A challenge presented, and only one way to defeat it.
Human endurance.
A small afternoon activity.
A step in the right direction.
