 That is amazing. They put the equipment on me, and one thing, they have what they call the smoke towers, so they have kind of a two- or three-story tower that you go in. They light a fire in there so it's smoky and it's hot. Oh, really? And you go in in all your gear and your equipment. You have your breathing apparatus on, but you basically have to feel your way along the walls to get in and out, and that's to train people that they often have to go in those situations. Mm-hmm.
