You know.........i had seen this in an article a few weeks back and i had to almost laugh. I mean..........being blind and deaf is no joke but.........this is ridiculus! I think they need to focus on something really worth while other than the fact that hybrids are quiet. The world around us is getting louder and along come hybrids and............WHAM! They get blasted by a group claming they are TOO quiet......please.
