"How can you explain that you need to know that the trees are still there,
and the hills and the sky? Anyone knows they are.
How can you say it is time your pulse responded to another rhythm,
the rhythm of the day and the season instead of the hour and the minute?
No, you cannot explain. So you walk."
from New York Times editorial,
"The Walk," 25 October 1967
Day 20! Wow! Who walked today? :-)
