That Superdome freaks me out. I would NEVER go in there! She and Shep are good friends, aren't they? At least they seem to be when they're both on. I can't imagine what the reporters were thinking, going in there.
You're right. No one should be inside any building with a large span roof in a wind storm like this....domed stadium, theater, gymnasium, roller rink, etc. The chance that the entire roof will cave in is very high. A building where the roof is supported at many points by a forest of columns or interior loadbearing walls is far preferable.
