Jones Soda is at it again. The new NFL-themed flavors are Dirt, Sports Cream, Perspiration, Natural Field Turf, and Sweet Victory. Natural Field Turf Soda is described as "like playing tackle football, and you get tackled really hard, you're down on the ground and you get a little bit of the grass in your teeth." Follow the link for a description of the other flavors.
