— “For some reason, I was terrified of looking up there and I don't know if anybody else has had that feeling, but it's (horns) not very friendly.”

— “ I thought that something really bad was happening. It was terrible. It shook the house!”

— “Did you hear a loud 'boom' last night (January 27, 2014) around 11:20 PM Pacific, especially in the College Terrace neighborhood? If so, you weren't alone. Our 24-hour dispatch center received several calls about it. Our officers did an extensive area check, but were unable to locate the source of (boom), nor any damage anywhere. We believe that it was most likely caused by an extremely large firework! If you have any information to the contrary, please let us know.”
