Has anyone tried setting up their own artificial structure? I tried this one day a few weeks ago. I used aquarium plants. I drilled three holes in a half circle and lowered the plants down with ice line. I put a fourth hole in the middle. I set a tip-up with a minnow in this hole. All of the holes were only about two feet appart. This was the only tip-up I did not catch anything on that day. I've read good reports and bad reports about this technique. Does anyone have any reports on this?
