Ruta Nacional 40, Argentina

RN 40 in Argentina makes Route 66 in the US look like someones driveway.  We drove KM4500 to about KM3800 in the Northwest of Argentina in the last week and it has been incredible.  Can't image what KM1 in Tierra Del Fuego looks like.  Even better, KM5000 plus near Bolivia.  Definitely going to come back down here someday!
