Why the Primitivo?

Well, because the more famous Camino de Santiago (the Camino Francés to us peregrinos) has become too famous, and therefore too populated.  This won't be a problem with the Camino Primitivo, which proceeds from Oviedo in a southwesterly direction until it joins the "main" Camino in Melide, a hard day's march from Santiago de Compostella.  Although the Primitivo attracts a goodly number of hardy souls in the summer nowadays, I expect it to be fairly empty at this time of year.
