Being from Florida, which is a hockey market, I think 30 degrees North is a good mark of where climates are cold enough to play hockey. If you look at all the hockey power houses, they all are north of this line.
But I believe there is a whole untapped hockey market, using 30 degrees South! There are 6 nations that are reasonably south of this line of latitude.
So I present to you, the Southern World Cup of Hockey! Here is the logo I made.
Here are the 6 teams that compete in the games, which take place in their Summer.
