Here's something I heard from a family friend. He was watching a construction site for days. When they were pouring concrete he was there as much as he could. He laid a tarp in the truck and the driver dumped a good size load on it for free. A 15 minute drive home to what he had ready. He had collected a lot of 2 quart to 2 gallon plant containers. Had rebar, aluminum rod and nylon rope made up to go in the concrete. A few hours later he had a yard full of habitat anchors.
