Heading west on highway 11 to brodhead seen the green county helicopter hovering over brodhead pretty normal they always come around. then to my left i seen another chopper heading south going directly over me wanting to get a better look i turn to look for the helicopter and the tree line ends at this point when i see "it" i don't know what this was but it was at least 4 times the size of the chopper and had two extremely bright white blue (like day light bulb) lights coming from the rear that flashed every sec or so. now i grew up hanging around a airport from time to time and there was no green and red lights and it was way to big and moving way to slow to be a plane plus the size of the lights would have been the entire wing of a passenger jet. i have no idea what i saw but two chopper where watching too the one followed it all the way to the il border. i guess because the chopper flew south stopped for a min then turned around and headed back. every1 can give me garbage for not having my phone but i was just going to grab some food quick and this is not a joke.
