Twenty to thirty minutes and I'm not sure exactly what's going on we have heard that part of the building. It's compromised. -- We tarnished. Yet what will have a better idea here as we swing around right now that the wind is blowing the smoke directly at -- so -- plan at the moment is to get around to the other side of this. They get a really good look at that spoke out of the way and be able to get a sense -- what's going on down the street level. -- and the worry too was with that thick thick thick smoke blowing right into those buildings. If and especially if if we have. I guess -- level to with the police and third alarm fire near Gallup.
