No Coke, No Pepsi, that's right -- Jones Cola. Sadly, the Thanksiving flavors are unlikely to make an appearance.
The article mentions that the other 31 stadiums are locked down by either Coke or Pepsi -- I have vivid memories as a child of Shea Stadium being RC Cola (maybe until 1991-1992?), but I can't imagine many other stadiums have had other soft drinks available in the last 15 years or so.
