adj. Devoid of direction or purpose.
I'm not going to log my miles this year. I've been tracking myself for several years now, so I can predict with reasonable confidence that I'll bicycle somewhere between 6,000 and 7,000 miles this year, and will drive somewhere between 5,000 and 6,000 miles. So I won't bore you with the daily details.
Instead, I'm going to highlight the unexpected, the unique, the serendipitous. Call it a return to randomness.
