I'm a freshman at the University of Iowa. My dad and I had just finished moving everything into my dorm room on the 12th floor, and we happen to look out the window to see this massive wall cloud boiling and rotating like crazy just north of the campus. We saw what looked like a funnel cloud coming out of this at one point, but we're not sure if it ever touched the ground. Great (and very scary) way to start off my college career!
