Our ongoing tour of Grapevine Mills dives deeper into the shopping center than ever before, bypassing iconic destination retail and entertainment offerings to drop in on an area few guests ever see: a fully functional police substation right on site! Hear from officers who patrol and train on the grounds (and the management who are thrilled to host them, even if a few TVs are harmed in the process) in this, the penultimate episode of 'Growing Grapevine,' Season 2.
