I prefer nero days over zero days, especially when the days are like yesterday. Tengo Hambre and I were done with our hiking by 10:30 a.m. We then had the remainder of the day to take care of town chores and relax.
To me, days like that are better than a zero because walking a little, even if it's a paltry 3.6 miles, is more progress than none at all. At the same time, I’m in a town long enough to gain nearly all of the benefits of a zero day. All I've missed is an extra night of sleeping in a real bed and a little extra town food.
