 is that they've got a rubberized sheet across the front of this tire stack, and they just used some self-tapping screws with some big washers on them to make sure that that outer layer, that outer skin, if you will, doesn't come unattached. They've taken care of that in about 10 seconds' time. Everybody heading back to the safety trucks. Great job by the safety team. They've got this all patched up and ready to go.
