Well, Well... A day of tranquility and chilling out isn't all too bad, every now and again. Colonia really was worlds away from Buenos Aires. It felt, if anything, like a smaller, more well kept secret, version of Visby. Cobblestone streets, old colonial portuguese houses, cozy wineries with hundreds of bottles.
In short: a nice relaxing day.
But when I got back to BA and started walking to the hostel I accidentally walk right onto what seemed to be a drum parade, which was impressive to say the least. 30 odd guys marching through the old neighborhoods of San Telmo, furiously banging the drum strapped around the torsos in a multitude of different rhythms. I got the impression that nothing was choreographed, it was solely a group of guys with drums who wanted to cross half of Central BA to the beating of African drums. And then a crowd came to follow them, snowballing until the crescendo and then suddenly dispersed.
Impressive, really cool and very lucky to walk into it.
