The same principle applies to the Puddle Jumpers, who ride their snowmobiles over open water. Preferably with someone nearby who can provide water rescue when (and note I don't say IF) things go wrong.
Stephen sent us these sort video clips he took at the Dorset Winter Carnival. And no, he did not skip -- he was the videograher!
