Wandering.

Wyeth, Jamie, Offshore Goose, 1994

Musing takes place in a kind of meadowlands of the imagination, a part of the imagination that has not yet been plowed, developed, or put to any immediately practical use.  Time spent there is not work time, yet without that time the mind becomes sterile, dull, domesticated. The fight for free space — for wilderness and public space — must be accompanied by a fight for free time to spend wandering in that space.

Rebecca Solnit, from Wanderlust: A History of Walking
