Crystal Z, weekday anchor of Jacktivities on 93.1 Jack FM, takes her fluff reporting seriously.  Like, she actually attended “college” and junk.  After an exhaustive search that ended at the bottom right corner of the country, and the very end of the alphabet, Jack FM found our bubbly yet affordable Crystal Z.  Not just a talking head, Crystal Z is out in the field attending Jacktivities and ensuring quality control of event concession stands and vending machines.  What motivates Crystal Z?  “I just want to get people off the couch,” she said wistfully, while eating ice cream out of the carton.
