Where is that, looks like a road we have ridden?
Yup, you're right and I wondered if you'd pitch up in this thread - you were helpful to me with a bit of advice ages ago. Unfortunately I took that advice and did, in fact, go to Patagonia. That pic is heading south on the Carretera Austral, south of Puerto Yungay on the way to Villa O'Higgins.
You will no doubt recall that the cycling was ghastly, the people wonderful and the trip utterly magnificent. I didn't go into Argie, turned at O'Higgins.
