The banner says "Govenor Patterson's beverage tax would increase the price of your favorite beverages up to 50%! The last thing New Yorkers need is another tax."
Notice no diet beverages are pictured. And it is on the back of a Coke truck. Interesting how the banner doesn't say "We are sorry for making sugary beverages that have packed on the pounds, America. We promise to make all of our drinks healthier so you won't have to pay more money out of your pocket because we are scared you will wise up and stop buying our fine drinks."
They would need a bigger banner.
