With temperatures in downtown Boston hovering near the 90s on Wednesday, the Bruins and the NHL were doing everything they could to keep the ice surface at TD Garden up to par for Game 4 of the Stanley Cup finals. But after Wednesday morning's pregame skate, members of the visiting Canucks said the heat and humidity already had affected the ice, turning it slushy and soft. "The ice wasn't very good at all," defenseman Kevin Bieksa said. "The ice is very soft and chippy. It's humid here. It can hurt you when you're coming up the ice and assume the puck is flat on your stick, but it bounces away. We just have to be careful."
