The benevolent souls over at Mission Mission came across this jarring, albeit all too common, story. It tells the tale of Jen, who, understanding that Mission Mission is the Dateline NBC of San Francisco, asked them for help. It seems that Jen and her boyfriend had this bike that "they both loved more than anything in the world," but it got stolen outside Safeway in March.
