I was in Sao Paulo in 2001 when Argentina had a coupe. I've been in Soa paulo when the prison population was rioting and this affected the whole city.
But this in Bolivia has been brewing for a while. Santa Cruz is very modern city with lots of construction and liberal attiudes. La Paz the capital city is very pro-gov't. I like VVI a lot. Fun place. I thought I read somewhere that the Bolivian president wanted to rid Bolivia of everything SPanish. And to go back to the Indian language. I think it was called the axa indian or incan language.
I think that might have been one of the final straws.
