Sounds like a great trip. Nice scenery!

Not certain which particular route you chose, but ... Just wondering, in the photo of you at sunrise (?) with the mountains behind you, is that the Anza Borrego wilderness just north of the US/MX border?

Of course, the trip all the way to Ushiaia, Tierra del Fuego, will be spectacular. Dang. Only way (these days) I'd ever be capable of making such a trip would be with a set of car keys. Envious.
