re: The horde has emerged, the Cicadavasion(tm) is in full swing

I literally thought I was going crazy. I walked around my house trying to identify the source of this mysterious noise that almost sounds mechanical (to me it sounds like a belt whine on a machine). I walked around my yard and could find nothing as the source. It seemed it was coming from all directions (yet still far away).

BTW, these sound nothing like regular cicadas. These things sound like they are screaming - it's a really high pitched sound and is nothing like I have ever heard before. It sounds like a belt whine or perhaps like a UFO landing. Seriously, it's really weird.
