I can't remember what she said would be better....to have the horses in a sturdy barn or let them out so they wouldn't be trapped in a flooded barn. I guess you wouldn't want them in a flood zone to begin with, but Flloyd was so bad it flooded about a third of the state.
With all the flying debris and just general nastiness (people can't even stand up in these storms for crying out loud) I'd never leave them out. I'd build a barn that could take it and would stay dry... If I was to live down there with horses.... which I wouldn't!
