There's a baby on the board...literally! Lots of parents ride bikes with their babes on the back, but I had to do a triple take when I saw a dad skating down the hill with his daughter strapped to him in a Baby Bjorn. While he was no Tony Hawk, the father clearly knew how to navigate the sidewalk on wheels with or without his wee one. But, how safe is it for an unprotected tot (tethered to a parent) to barrel down the streets of San Francisco or those of another city?
