We crossed the border between Argentina and Chile at Chile Chico on 29 March 2008. We drove west until we hit the Carretera Austral and then turned left.
For the next 87 days we were in wet, foggy and chilly areas of Chile.
We spent a portion of that time in the rain forests of Chile, where annual precipitation is measured in meters, as in multiple meters of rain per year.
