Hello Steve,
Still keeping an eye out for problems and protests here in South America. I was on my way home right at sunset and saw this. I am not sure if it was still building and growing in size or if it was dying down. I rode around it and then show the news crews toward the back of the crowd.
I let the camera run after I showed the protestors and then I went around the back of the Casa Rosada (Pink House) too.
I am not out every day, but if I were, I could certainly find one or two 'bolonquis' happening if I did a quick circuit around the city, more if I went out to the surrounding areas.
Even the word is messed up - original is quilombo
