Being from the land of ice and snow, I thoroughly enjoyed the old Chicago vs. Minnesota games. Some of the best fighting I have ever heard (used to listen on the old AM radio going to bed) and seen. Al Shaver was an unbelieveable announcer.
The Boston/Minnesota fights were some of the best also. I can remember one game in which each team was down to like 7 or 8 skaters going into the 3rd period. The fighting started before the refs even hit the ice in warm ups.
