An acquaintance of mine was headed to kentucky derby a few weeks ago and had just set up camp in Athens, Alabama when they were under a tornado warning. She heard a banging on her door and it was a civil defense worker there telling them they had to grab their dogs, get in the car (class C with a toad) and follow him. They (all from the Rv park) drove straight toward the large funnel cloud and then parked at the storm shelter, went down into the "bowels of hell" as she called it with several hundred of her new best friends and had to stay down there for 3 hours. When they returned to the RV park, all was well but they had left the windows open in their haste and so had to clean up the flooding in the class C. Oh, they had trouble getting back to the RV park since trees, power lines, etc were down so they used google maps to direct them in a roundabout way to get there.
Of course, this isn't about driving in bad weather, but I thought this was a very interesting story about what happened to her....
