Every week, we do a minimum of two, plus we have employees on the trains who tell us what's going on. There are hundreds of thousands of inspections of the railroad and cars, plus automated sensors and ultrasound. I would say that it's in the hundreds of thousands in each area. It truly is. We have a lot of inspections going on using a wide variety of technologies and people.
