This is a generic citrus soda. It is very similar to Mello Yello and Mountain Dew. It's not as good as those two drinks but it's close. Mountain Lightning is cheaper because it's generic.
If you like Mello Yello/Mountain Dew, try Mountain Lightning. It is refreshing and it will save you money. You can find it at Wal-Mart. I give Mountain Lightning a 4 star rating.

If I remember my Burt Reynolds 'Gator McClusky' movies from the 70's correctly, Mountain Lightning wasn't a soft drink.
