So I have few friends in warm and friendly land of Argentina and they're (surprise surprise) really into bikes. Mati Kalwill is a regular at the Critical Mass over there. I've never been to Critical Mass in London and myself am in two minds about the whole idea but it looks like they're having a good fun having it and manage to piss off load of taxi drivers and buses which we all know is a good thing. oh and of course, manage to make the point and usually get a lot of cheering from passer bys (something that's definitely missing at any London based public action). Mati also runs great bike blog, check it. and is part of a bike collective Biciconga.
I am also very keen on their combination of CATS and BIKES - fuck yeah, match made in heaven!
Vanessa Bell, my friend from London that currently lives in BA posted a nice write up on her first experience with Masa Critica on her blog and it's a good read. I'm looking forward to more reports from her, watch her blog!
