Though I am not a pop lover, I found this segment very interesting.

That was great. I watched about half the video.
One of the great benefits of buisness travel is getting to try different, regional sodas. (forgive me, Southern Bretheren. "Cokes")
The best soda I think I ever had was a lemon lime concoction while I was in Zimbabwe, the Summer of 1993. We drank it all Summer. Man, I miss that drink.
I'm not sure if it's still there, but Epcot had a display (I believe funded by Coke) that showcased many of the sodas from around the world....they might have that one...I remember a few odd ones and a few good ones, but that was years ago.
