I lived through a F-5 tornado on June 8, 1953. I can testicle they are no fun. Come to think of it, Neither are floods or fires.
In the California flood last week, water stated coming into my son's friend's house. They got it sand bagged after about a of foot of water came in.
The day after they got it dried out the mold was already growing on the furniture. I never thought of a problem like that.
