Great riding but...
...not to call the cast up for an encore of "why no vests", but good lord - these dudes - WHY NO HELMET? Riding without a vest is a bad idea but hitting objects in any boardsport without a helmet is showing terrible judgement.
The stuff they are doing is no joke on some of those sliders. Great, skilled riders many of whom have terrible judgement.
Personal choice, yes, Live Fee or Die Hard With a Vengeance, but it is still a bad idea.
