Watermelon is thought to have originated in southern Africa, where it is found growing wild. Today I had a chance to try a Big Train Watermelon drink. It was the pinkest drink I have ever seen. This made me think that this would be perfect for hosting a baby shower or bridal party that needed a frosty, coffee-free beverage. This drink did have a very strong watermelon taste while still holding a creamy constancy of a milk shake. I do enjoy watermelon but -to be honest- this was a different idea to me, a watermelon flavored frozen drink? If you were a diehard watermelon fan this would be a must-try.
