cultural subtlety

mountain dew baja blast has been around for a few years now. but only at taco bell. i discovered about a year after trying it that it is a lime-based flavour. i have not done any research about this but i wonder if the drink is a taco bell exclusive.
as a side note because i know i have not documented this yet in any way (i think) is that i continue to like the taco bell sauce packets with the funny phrases on them. including the purple one that replaced the orange hot colour that was out about a year ago for feedthebeat.com.i suppose the packets will be discontinued eventually, probably soon. but it has been nice to have a little “flavour” like this in the popular culture mainstream.
