My first week "up here" near Huntsville, AL, I experienced a few tornadoes. It was... surreal. I'm used to hurricanes and have sat in my front porch swing watching the trees get blown up the street, but tornadoes are a different beast.
I watched the tornado that went through Enterprise, AL, a few years back. At that time I worked at a weather radar manufacturer and someone there actually called it in (if I'm not mistaken).
I have a lot of respect for these storms now.
