Global warming is real, so a real 11-city tour (is this an accurate translation) will be difficult to achieve. Luckily we have an alternative: the Alternative 11-Bar tour (again, don't know how to translate this).
Anyway, hop around 11 bars with your group and a bottle of anything that helps you keep warm. Maybe you'll win a prize, but at least you'll have a fun night.
More info will be anounced on Facebook and on this page.
