I'll tell you this, its a good thing I had line of sight with the drone I was flying recently, or it could have gotten ugly. Bottom line is drones exist and they aren't going away, and as much fun as it is to fly a helo in the weeds (believe me, I know!), that is where the drones are. The best way to avoid an issue is for the drones to stay low and the helos to stay high. For reference, my drone was about 30' off the ground in this video.
