While at a vacation in Basel, CH. I decided to visit the local hackerspace, Chaostreff. Chaostreff is located in a basement of a apartment building, and next to piles of mate, pinballs and blinkenlights they have their own fallout shelter! I was received in the friendliest of fashion, and they also brewed me a Tschunk. I can strongly recommend it!
We are al invited!
