I live on Hearst Ave and Detroit is my side street. Every Monday,Wednesday and Thursday morning at 4:45 until 5:00 I hear a buzzing sound. I have talked to my neighbors and they to hear the noise. We are trying to locate where the sound is coming from. He can be very annoying and scares you awake. The noise is quite loud because I have stood on my porch trying to locate it. Does anyone else who lives close by hear the noise and have any idea what it is?
