Me too, but I must have missed any report of what happened to the driver on the back of that Zamboni.
I think the driver is now orbiting Mars.

Joe Buckley, the driver of the Zamboni, which resurfaces the ice, said he was sweeping up when the blast occurred.
When I first read the headline, I mistook Zamboni for "Zambelli", the family famous for making fireworks. I thought fireworks had exploded and caused an arena to burn down.
