How much, or in what ways, do you direct the attention of the walker?
Is the walk a container explicitly for heightening attention? To what?
Attention to the sensory experience of walking: to the body of the walker.
Hard attention: directing the walker to points in the landscape with the intent to reveal something about it.
Soft attention: an all-over awareness, walker as moving point within a field with a multiplicity of meanings and beacons.
