The bad thing about these idiots... Is if they slip some innocent person is quite possibly going to get killed by the moron precipitating from the structure he is not supposed to be on. But that’s the way this world is now, everyone thinking about themselves and not about what effect their actions may have on everyone around them.
I have to compare this to free solo rock climbing, which in many ways is identical. Up high, hanging on to not very much, certainly dead if you fall. What separates it is what flying squirrel said...what about the impact on others, including the owners of the property on which you're spread all over.
