Calgary's premier sports arena is home to hockey games, the Calgary Exhibition, and the 1988 Winter Olympic Games. This last event is important because it was the Olympic Games that helped shape the building. It had to be built to accommodate international-sized competition surfaces. The building's shape makes one think it could be called an anti-dome, but people who live here love it and consider it a source of pride. They're not always as enthusiastic about the teams that play here, however. 6,000 acoustic tiles were added to the roof to make it a better venue for concerts, but the effect was it also absorbed crowd noise. Bad news for local team who already have a hard time getting mass support from the locals.
