For the last six months or so between 6:30 and 8:00 PM almost every day we've been hearing a weird noise that we thought was some sort of bird. Normally the noise flies quickly downriver behind the house (our backyard is a river). Sometimes it flies up river. Always the same time of day. Tonight I just happened to be outside from closing up the animals for the night and I heard the noise. Instinctively I looked up and it flew right over me, and our house, at tree top level. We have Fir Trees so I'm guessing it was about 60' off the ground. It surprised the hell out of me. I've just spent the last hour researching online and I finally found it. This is what has been making the noise we've been hearing fly around in the early evenings since about the end of September. The Insitu "Night Eagle" UAV. I know that there are a few Insitu locations out in Yakima. I didn't know there may be some in Clark/Cowlitz. My wife just came in and said it flew back over going the other way just now while she was out smoking.
