Don't know about the rest of the country, but most gas stations in small, buttfuck southern Missouri towns have Mountain Dew and what they call "heavy dew" available at the fountain. The heavy dew is like 95% syrup. The small town teenage meth crowd with the big honkin' hot topic pants that I used to work with loved that putrid shit. I hate this fucking state. Theres a city on the east side sharing space with Illinois and a city on the west side sharing space with kansas. Everything in between is hundreds and hundreds of miles of God,meth, pickup trucks, overalls and firearms.
