Walter's love of Red Vines on Fringe got me thinking...
In high school, my classmate's father was an executive at American Licorice. We had Red Vines at every school function, dance, etc. I might be showing bias, but I can eat Red Vines until my bowel movements turn red with artificial coloring... Red Vines don't really taste like any natural flavor, perhaps mildly similar to generic red fruits. On the other hand I can't stand how Twizzlers taste or how tough they are to chew...
I fully expect everyone from the East Coast to choose Twizzlers since Red Vines aren't widely available there.
