Ladies and Gentlemen, I bumping this thread up.
The Pepsi and Mountain Dew Throwback started arriving on store shelves in my area last week or so. For some odd reason, Walmart is not stocking it at this time, but most every convenience store is. I don't know about the smaller grocery stores, so I will have to check them out soon.
The Pepsi is pretty good. It doesn't seem to have the "bite" that the HFCS version has.
The Mountain Dew is kind of strange. At first sip, tastes closer to the Diet Mt. Dew (horrible stuff in my opinion) but tastes pretty good once you get used to the difference.
I heartily endorse this move of Pepsi, and hope Coca Cola does the same thing soon. None of the stores around here stock the Mexican or kosher coca-cola.
