Talk about riding the wave

Most people, when a fast-moving rain line comes racing right at you, would seek shelter. But where's the challenge in that? Scooterdude (you know, the guy who flies around Copley Square on his sail-equipped scooter) reports he rode that wave:

... The best way to describe it - catching a huge wave of 'surf' and managing to ride it four to five blocks before an unfortunate fall at Arlington St. atop a manhole cover. There was just enough time to pick one's self up, see the solid sheet of water approaching, and race to the shelter of the T stop.
