I think i would do ok apart from the other people there. I don't think they'd survive very long.

We regularly talk about this sort of thing at work. It's interesting seeing different people's levels of preparedness. We're due to fly into Florida with work next week. Will be interesting to see what Hurricane Irma has done to the place.
