To the Argentina/Boliva Border

Hola! Yesterday I supposed to go to Santa Cruz, but whan came to Retiro station in BA, the officer told me, that isnt possible to go to Santa Cruz today, mayby tomorrow, so I changed my plan again and have return to previous plan - go to La Quiaca at the Bolivian border, than Ill see what next. In one hour I was in the bus to La Quiaca. First the journey was too borred, there was nothing to watch out of the window, all the time the same view, but whan I woke up next morning, I had nice view at the mountains, the country had totally other image, than we went through Metan, Salta, San Salvador de Jujuy and Tilcara and at 3 pm I was finally in La Quiaca. Its small town where is really nothing to do, who can goes directly to Bolivia.
