Mountain Dew is my favorite soda, I love how it comes in many different flavors here in the US. I couldn't drink it when I was too young since it's got way too much sugar in it for a young child! Once I was a preteen I was allowed to drink it. This was right when Code Red came out, I remember getting it from a gas station and being blown away with how delicious it was! Then in 2004, I tried Livewire and that became my new favorite soda. I still love Mountain Dew, and my favorite flavor was Typhoon but it's sadly discontinued... It came back for a short period of time last year. I also love Pitch Black, and it came back for a little bit earlier this year and man it was just as good as it was in 2018! (The original Pitch Black that came out in 2005 was disgusting though!) The only flavors I don't like other than original Pitch Black are Spark (bleh that just needs to be discontinued, it's a sour lemonade flavor), and Fruit Quake. (This was the seasonal one that came out last year... yes it tasted like fruit cake. 0/10 do not recommend, if it comes back...) I think any sour flavored Mountain Dew just doesn't taste good. I've been on the lookout for the new Summer Freeze flavor, but it literally dropped the other day so I'll need to look again this weekend. It's supposed to taste like a bomb pop!
