OK, ladies and gentlemen, here we go again. As the earth's northern hemisphere begins tilting towards the sun, whose rays start striking the Tropic of Cancer at 23.5 degrees north vertically, the cola wars begin again. And of course, this year they are bigger, noisier and more violent, with both sides packing more firepower and spending more money than ever before. Please settle down in your ringside seats and let the good times roll. Incidentally, Coke's theme for the season is 'Red Hot Summer' and Pepsi's 'Cool Cool Summer'.
