No Politics- Just Crystal Pepsi! One of my favorite protestors of the Denver DNC were these guys from bringbackcrystalpepsi.com. They had a good sense of humor, but some of the other protestors were upset they didnât take things a little more seriously. I thought they were hysterical, especially the lines about shock treatment therapy for dealing with a Crystal Pepsi free soda aisle. I, too, would like to throw my support to the cause and lend my support to the crystal pepsi cause- bring it back!
