Armand drives-I read & sleep.  My turn to drive–after 2 hrs my eyes are sleepy–not much help.  Armand drives most of the way.  Stay w/Bob & Donna in house Bob built while he lived in bus for 4 yrs.  After wonderful meal Donna cooked-took walk w/their 2 dogs–nice visit.  Bob & Donna had completed a 10 week hiking/back packing trip in Patagonia & other parts of Chile–not something I could do or would want to do!!!!!!
