Well if you're writing a tornado song Aine.....You might include the 40 or so campers plus about a dozen dogs and a few cats all huddled up in the concrete block 6 stall showerhouse....and you're right about the sound, but have you ever listened to a steam engine hauling hard at speed? I think that's the sound they were referring to. I guess diesels took some of the "romance" out of tornadoes too.........Spaw
