This morning at about 3:30am, I heard this horn sounding in the distance. I thought it might be from CalTrain, but then it just kept on sounding every 20-30 seconds or so. It sounded like it was pretty far away, but it was still loud enough to keep me awake, which I definitely did not appreciate at that time. I feel sorry for those living closer to it.
Did anyone else hear this? Does anyone know where it was coming from? We can't be woken up in the wee hours of the morning by stuff like this. Please, somebody, make it stop!
