Zello saved my Coachella camping group! I direct a caravan of 15 cars from a superstore parking lot to the Coachella camp grounds each year. It’s a challenge as there are many traffic lights that can split up the group and a few turns. Thanks to this app I was quickly able to alert 2 cars that got off I-10 at the wrong exit and they were quickly able to rejoin our group. (no one fessed up to it 😝
