I have seen skis similar to this a few times. I have to say it can be a little frightening. Unlike a storm, where you know the "what and why", It was calm for the most part when I saw it. And I don't think it was "normal" for where I live.
So I ended up thinking to my self, is this going to knock my house down, or strike me with lightning? Nothing bad ever happened though.
Its funny how nature can humble you even when its not violent.
