Michael Miller (of Cache and Release) joins The Bad Cop and DarrylW4 for the two hundred twenty-first edition of the GeoGearHeads. This Randomize edition kicked off with feedback from Michael that Looking4Cache (Pro and Lite) supports logging with unique logs, trackables, and photos for each of the accounts signed in through the app. Next up was the news of the "Geocaching International Film Festival 2016." Videos from the previous GIFFs are posted on the official site, and the entire 2015 reel is on YouTube. Then it was onto several articles about global positioning satellite systems;
