What kind of a sane parent would allow their child to break the speed limit on some extraordinarily precarious roads, on a skateboard? I'll say this right up front, this isn't by choice. He'd do it with or without my approval. Not that he is at all disrespectful, he's far from it. In fact he is quite a sweetie. He loves to race. I know I have said this before, but it is still true. So, as his doting parent I supply him with a firm set of rules.
A) no helmet= no skateboard. This is an easy one to enforce as the whole of our local longboarding community is in support of this one.
