I have an App on the iPhone that lists campsites in Italy… just not all of them! For example there is a site in Pavia but it isn’t mentioned on the App. Notwithstanding, I’ve just put lots of little triangles on the map of sites between here in Pavia and Rome. I reckon it will take me about a week to get down there. Then, after a day off in the capital, another week to get down to Puglia with a day off, of course in Benevento to meet up with Massimo.
