An old friend of mine sent me an email with some of these slides.  Now I have an adventurous spirit, but...

I live in the South L.A. area, way South down in Orange County.  I really don't like traffic here but you know,,  I really don't have much to complain about.  This is a Bolivian road over the Andean mountains.  It is a major thoroughfare and it is a one track road.  Whenever you come to oncoming traffic, the guy climbing has the right of way so if you are descending you've got to find a space (good luck) to move over and let the oncoming traffic pass.  Oh, and one last detail.  The rule of the road here is keep left.
