It wasn't a deathtrap at the time - and the good news is that the SD is still going to be pretty much above the level of the lake anyway. The field will flood, but that's about it.
I don't know. Pieces of the roof breaking off and now this. I would NOT want to be cooped up with 15 thousand agitated people. Maybe it won't flood, but how do you feed everyone and maintain order in that space for days?
