These drone pilots are competing in a new high-tech sport that's taking off around the world.
They wear first-person-view goggles that let them see from the drone's perspective.
Colby Curtola: "It's completely immersive. Once the goggles are on. You're on the drone. So as soon as you take off, you know, you feel like you're flying basically."
Amateur drone pilots are finding unique locations to race like this abandoned train yard south of San Francisco.
To compete, you need a fast drone, quick reflexes and good hand-eye coordination.
