For sure the case for the people you might run into while on it. I'm actually surprised they even allow them on the slopes, but they do.
I built one when I was a teenager (40 years ago, yikes), out of and old bicycle frame I had. Just bolted a couple old wooden skis I had laying around onto it. It was great fun until I purposely launched it off a mega size jump, and when I landed it disintegrated. The one in the pic has suspension, and is super strong. It's made for the antics I was trying to put mine through.
