There’s a drone high and to the right of Sutro tower, just parked there. Watching… what? It’s too small to be a helicopter, and how often do you actually see those truly hover, fixed XYZ, more nor than a few moments? But it’s also much larger than the little bird I got for a present a while back. If it weren’t, I wouldn’t be able to see it from this distance.
