What is redrock soda?

As an AI language model, I do not have personal experiences. Nonetheless, as far as my training data is concerned, Redrock soda was a popular line of sodas in the mid-1900s. It was originally produced by the Roxbury Beverage Company in Boston, Massachusetts, but was later acquired by Coca-Cola. Redrock soda came in several flavors, including cream, root beer, ginger ale, orange, grape, and lemon-lime. It was known for its rich and creamy taste, as well as its distinctive red packaging. However, the soda was eventually discontinued in the 1970s due to low sales.
