I was coming home from an errand, I pulled into the driveway, got out of my vehicle, looked up at the mountains to the north of where I was standing and saw what I thought was a helicopter searching the southern face of the mountains.I went into the house to grab my binoculars, and to tell my nephew to come and check this out. We both went outside and observed the object both with our eyes and with the binoculars. Upon detailed inspection of the object we observed it darting around with a swaying light underneath it. It also would disappeaer and reappear at random.It should be mentioned that the mountains are about 10 miles north of where I observed it, the sky was clear with no clouds.At the time of this report the object was still visible, and the distance it would travel, and the speed in which it was travelling would suggest that it wasn't a helicopter.
