I created a little structure of my own in one of my ponds. Essentially criss-crossed two logs, creating an open triange in the middle, in which I propped/sunk an old christmas tree. I put more branches on top of everything, and weighted down the ends of the logs with rocks. Caught a couple of bass off of it, but it's chock full of bluegill now, and that's a good thing, because it attracts bass to the area. Took about an hour to make and it has improved the fishing, if not drastically.
