I've had one turbine up for over a year, two up for about 6 months, still haven't gotten my first bird ;-), two behind my new dog, a few behind my car... It's time to do what any intelligent individual would do and outlaw wind turbines, dogs, vehicles, clean windows,...save a bird at ALL costs. ;-) Makes you wonder if Big Bird is more than just a character on Sesame Street. Bird brains rule!!! LOL
