While listening to my police scanner I heard the following dispatched - (address was given first, to which I unfortunately was not listening closely to) and then the dispatcher said it was reference a large light in the sky, changing shape and changing color. The officer who took the call jokingly asked if there was a code for "the twilight zone". Although I went outside (it was about 11:15 pm, Thursday, September 28th) I was not able to see the light. Heard nothing more about it on the scanner. The night, however, was beautiful, the clouds were white and the sky which was visible was beautiful. In this area we experience on the highline wires a spider web looking substance (much too heavy for it to be spider web). This substance hangs from the wires until the sun comes up and burns it off. Any connection to UFOs?
