Book another night in Tucson and take the day off. From riding and writing.
In “Desert Solitaire”, Edward Abbey notes:
“A man on foot, on horseback or on a bicycle will see more, feel more, enjoy more in one mile than the motorized tourists can in a hundred miles. Better to idle through one park in two weeks than try to race through a dozen in the same amount of time. Those who are familiar with both modes of travel know from experience that this is true; the rest have only to make the experiment to discover the same truth for themselves.”
