We have shown a lot of their photos at English Russia. They call themselves climbers, but in fact they are potential suicides. Fear of heights does not exist for them, they do not even know any instincts of self-preservation. Joking with death is just their favorite game. For example, climbing old rusty stairs on a 300 meters top without a safety net or running on the edge of a roof of a 40 storey building. They do it not for any sporting interest or records, they simply like to have fun together in extreme conditions.
There are 200 of them in Moscow today. But their number is growing. Most of them are students.
They use different ways to get on the highest buildings, sometimes they find an unlocked door, sometimes they invent more extreme ways.
The best is considered to be photographed while being in a risky pose, in the balance between life and death. Here the guy is balancing on the height of several hundreds meters for a successful shot.
They follow two main rules: not to be afraid of heights and be sober.
