Rocky Top Dr Topper can found at Dillon's Supermarket in Lawrence, KS, Brookeshire Bros. in Houston, TX, and probably at many other stores as well. Dr Topper claims that you will "reach the peak of refreshment," but don't get your hopes up too much. Dr Topper tastes pretty good, but I would have to categorize it as a plateau halfway up a mountain rather than a peak. Dr Topper earns a three Dr Pepper can rating.
