That doesn't really make sense. The Zam smooths out the ice. It wouldn't be very good ice if it just melted and refroze on its own. The only reason you wouldn't use a Zamboni is if you didn't have one.mzheng said:It was said that in Moscow or Rusia during the winter, there is no need for Zombinie machine. When the ice surface melted, they just open the rink door, the ice will 'resurfaced', and the ice surface is much more hard than it is in US.
