I have been to a couple of CCC events in my late teens'ish. Around 26C3.<p>Over all can recommend, at least as a groups. I used it to meet some online friends for the frist time. Wifi / wardriving nerds that I spend a lot of time with online.<p>But man, I think I have never been at a place with so many small negative experience with other people. Death by a thousand paper cuts. One older man out of nowhere loudly proclaimed I was Anti-semetic, because I was wearing a Palestinian keffiyeh. When sitting in the cellar in the "hacking area", friends of mine and me where coding on kismet or aircrack-ng, when someone from the neighboring desk asked what we where doing. After I told him he only lifted his nose slightly and with a smug smile said "Oh, that's what you call hacking today?"<p>At one camp, where there even was an event on photography, someone I met almost went into a rage every time he saw a camera. Not pointed at him, just someone with a camera. Off he went to tell the camera owner about how it was last camp and his opinion ..<p>Everything just minor interaction. But as a whole it's just not people I want to hang around with any more.
