<human>: Can you give me the gist of the text in a nutshell?

So this weekend as my wife and I were returning from a walk with our doggie, we look up and notice what appears to be a silver or grey kind of kite sitting in a tree in my backyard, probably a good 100 or so feet up. It's pretty damn tall, probably about only 20 or so feet from the very top of the trees. Whatever it is, it was metallic and in the shape of a diamond.

I went out back to my deck to see if I could get a closer look. The surrounding trees pretty much obstructed whatever it was I was looking for, but I DID get a good view about ten feet below the object and there clearly was some sort of metal tubing snaking down the side. My view of the metal tubing (silver) eventually was covered again by the surrounding trees.

This morning it was pouring. I took my dog out back to pee and while I was out there remembered the thing in my tree. I go over and no bullshit, there seems to be a black, thick extension cord thingie coming down off the tree and disappearing into the brush behind it.

I have NO IDEA what this could be. My backyard trails off and it becomes a drainage ditch for when there are downpours. This ditch extends the entire length of the neighborhood. It might have something to do with that. My conspiratorial mind says it's some sort of listening device. My father-in-law thought it could be a lightning rod. Getting a picture will be pretty tough since the only way to see it is to stand about 50 feet away from the front of my house and it's in the backyard at the top of the tree. Any ideas?
<bot>: Discovered a metallic diamond in my tree in the backyard with metal tubing coming from it. Found out this morning there is some sort of cord running all the way down the tree into the brush behind it.
