 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 all, let's say your pickup truck. And, uh, the bear walks through the barbed wire to get a donut and we have a, you know, scent attracting and usually two donuts hung on a string in the middle of the snare.
