Just to put it in perspective.

Locate Bolivia.. I was at the lake in Bolivia last friday. By next monday, I will have gone from there to Buenos Aires, Argentina. Then Buenos Aires to Santiago, Chile (to go skiing), and then from Santiago to Machu Picchu, Peru. Wouldn't it have been a little easier to go from the lake in Bolivia directly to Machu Picchu?? Perhaps, but that just seems lazy..

(Mind you, South America hasn't had a cunning leader such as Mr. Eisenhower implement a worthwhile highway infrastructure between all of these points. Most especially in Peru and Bolivia).
