Hi, Jill,
Thanks for your journal notes. I didn't remember that you had been on the Norte so recently!
I think that the official camino route is shown on this wikiloc track
https://www.wikiloc.com/wikiloc/view.do?id=14990635.
The notes on the "alternative" I posted explain some of the differences if you scroll down below the map itself. It looks like most of the differences are before the Playa de Silencio but I have a hard time comparing on my ipad. For instance, the alternative goes through Valderedo, the official does not. If you compare the two, you'll see that they go in different directions leaving Soto, and for what it's worth, the person who posted the alternative just raves about it. I'm not sure if these are big differences or not, but when the guy writes about how it is a "stretch of the Camino that the years have forgotten" it makes me want to try it. It is also possible that the official route has changed since these "alternative" tracks were posted in 2010, so that the differences are now not very big.
I was not planning to bring my GPS on the Norte since it is so well marked, but having some of these off-camino alternatives on it would make it much easier to go for it.
I know I sound like a real asphalt-whiner, but I once had to stop a camino because of it and have since then gone to whatever extremes I can to avoid it!
Buen camino, Laurie
