WHAT'S your wildest dream? Emu Heights couple Tania and Steve Lewis say their life's goal is to light a cauldron at an Olympic opening ceremony by fire breathing. They met through a fire-eating and fire-breathing class in England two decades ago. The British Sun newspaper offered them 20,000 for a front page picture on their wedding day. They declined but still had a fire-themed wedding cake. The novelist and specialist engineer fell in love with the Nepean area when they moved here a few years ago with their son and daughter. They still do fire tricks for fund-raisers in Sydney.
