 You can put all that into a mathematical formula of how many that you've caught that have been marked and how many that are new. And you can come up with a population. So the way we do that, we call it hair snares. But it's really a two-strand barbed wire fence about the square footage of, oh, let's say, your pickup truck. And the bear walks through the barbed wire to get a donut. And we have a scent attracting. And usually two donuts hung on a string in the middle of the snare.
