RC is a regional thing. You can't find it outside of the southeast. And even then I couldn't find it to save my life in alabama. But it's common as fuck here in Kentucky.
Never tasted it. Altho, in terms of grossest thing, nothing I have tasted is worse than Monster, that shit just feels like straight up rat piss.
I drink monster just to wake up every day. I think that's what I miss most about being a kid: wanting to be awake.
