 somebody who's an inspector that's been inspecting the structure, and we need two-hour folks. So that's four people versus 15, 20 people that are usually on site. Right, right. So that's already reducing the personnel needed at the inspection. And then we just need to do some steps to make sure that the robot can get off the weird inclines or whatever they have. They're all different. I can't even imagine the next thing we're going to see. Some of them have very rocky outcrops, so you have to somehow drive over rocks. So it depends.
