Potosi
Trip from Tupiza to Posoti by bus has been really hard...We first wait all nigth a bus that never arrived... Then many problem with the bus, (3 wheels changed) on a very dangerous mountain road...
Potosi is not like others Bolivians cities. It is less clean, we heard a lot of "Gringos bastardes". Potosi history with a lot of mines exploitations by Europeans can maybe explain this.
I never saw a so contaminated city. I saw a river like a silver river, same color, same aspect. But anyway, some houses and buildings have beautifull architectural contructions.
