I thought, 'Oh, this is incredible, because that's where I was the previous day.' So, a lot of different thoughts went through my mind. I was grateful nobody got hurt.
This wouldn't be common at all. I saw that buckle on the east side of the roof -- 8 to 10 inches. That's the first time I've ever seen anything like that.
Especially at the corners, where the corner joints had opened up as much as two inches at the top.
It was obviously teetering on the brink of collapse during the time that I was there.
