black soda? has anyone else tried this new mountain dew flavor, pitch black? it is touted as mountain dew w/a black grape infusion. are there really such things a black grapes? i've seen black cherries, but not black grapes. normally, i fully support mountain dew's attempts to branch out. code red was good. livewire is outstanding. pitch black...well, let's just say it tastes like a non-alcoholic jaegermeister. yuck!!
