I remember a blue Pepsi that was hella fucking good back when I was in high school. I miss that. It was a pretty sour berry flavor; might have been blue raspberry but it was also pretty unique and one of the sweetest, yet still tolerable, sodas I've ever tried.
I also miss Dr. Slice. It wasn't a Dr. Pepper knock off; it was an official mix of Dr. Pepper and Slice. Not sure if it was orange slice, but it was better than regular Dr. Pepper and I only ever saw it at one random ass restaurant in the small town I had lived in most of my life.
