I was standing outside a minute ago when a Cessna 182RG or 172RG flew over me really low. I could barely here it though. Sounded like it was in idle. So I keep watching it fly off, then it turns around and flies back the other way even lower, faster, and I couldn't even here the engine this time. It flew past a small mountain and turned again. It never came back. I am wondering if maybe it went down in a valley nearby. I did see a plane go by way up high in the distance a minute later, but it seems that this plane was too high too soon to be the one I saw. So I'll just have to wait for the news to find out for sure. I am kind of doubting it went down though.

EDIT: I was out there again right now. And the plane flew up, circled a few times where I thought it went down. then disappeared in the same place as before. It obviously didn't go down. 

EDIT 2: Just saw the plane again. He was up at a normal altitude. He was coming from the same direction. Using my binoculars, I think it was a 182RG. Just a guess though.
