Even with the heat, it's game on for hockey at Dodger Stadium

Pipes from the truck will circulate the coolant glycol at the rate of 1,000 gallons a minute through ice pans set up beneath the ice. The glycol is recirculated through the system in the truck. The goal is to keep the ice temperature at 22 degrees.

Sensors constantly monitor the temperatures of the supply and return pipes. Craig has an "app" on his mobile phone that monitors the system — as well as the air temperature and dew point — and will sound an alarm at the slightest fluctuation. He falls asleep with the phone on his chest, set to vibrate, so it won't wake his wife.

The principles of the refrigeration system, he said, "are the same as your fridge at home, but on a bigger magnitude."

Much bigger.

For Craig, the reward isn't doing something that seems impossible; it's making the impossible look ordinary. He will get his first reviews on Friday, when the Kings and Ducks practice on the outdoor ice.

"The satisfaction for me will be when the guys skate out there," he said. "Nobody has to tell me. I'll know well ahead of them what they're going to feel, and I'll know from how I see them skate and how I see their eyes and the expression on their face. When you get guys from 19 to 39 just grinning from ear to ear and loving being out there, that's what we do."
