I am pretty sure about the changes, but less sure that the old route is gone. Several times the main direction had new signs for the new section, but from the other side hikers were still (mis)guided to the old route. Also, old sections tended still to have the signage, just not maintained. The fact that there are several signing systems, which do not always agree, doesn’t help either. Still, I will do what I can.
(side note: water levels in all natural rivers and streams were incredibly low to non-existent! Still nature seemed to find enough water, and the system of canals and microcanals for irrigation of maize and sushi rice fields still provided enough water. Nederland could learn a lot from the Italian system! We are very good at pumping water away, but not so much at retaining water, which means we suffer much more from hot dry periods and low ground water levels.)
After the VF-sections we did the San Jacopo Cammino Toscane, from Lucca to Firenze. I have kept notes and made many snapshots, so I think I can improve lots of details there. One issue: The predominant symbol is not the Shell, but the orange and yellow paint stripes. Orange in one direction, Yellow in the oter direction. Only one of them (yellow, to Livorno) includes the shell, but not consistently. The other system, Arrow stickers and shields, also have yellow (and a pelegrino) and orange (and a Roman) for the directions, but these often rely on the painted signage in the absence of poles and the like. And there are also old stone markers… The point is, I don’t thinks the shell actually is the main symbol, I think the orange-over-white is the main symbol for this two-way route.
Also, the Cammino is international, but this route is tagged as regional. Is that correct?
