Where did you hear this? WOWK has not reported it yet.
I just Googled “Horse Cave KY” a while ago and it had links to a couple of news reports saying the people had all gotten out safely. One was WBKO. They were out by 4:30 p.m. (I think that would be Central Time—that county is in the Central Time Zone but very close to the border with the Eastern Time Zone).
