I haven't seen one in the flesh, but they're common in Iowa where I live. Usually during the spring/summer they usually inform us if there's a tornado watch(Meaning there's a chance for one) or warning (Meaning there's one on the ground or near the ground).

I'd say the last tornado that went by me was about 1-3 years ago. It was late at night (about 1 AM) and I was in a pissy mood because I was a teenager that wanted to go to sleep but I had to wait the storm out in the basement (and the siren that was blaring, alerting the town there was a tornado warning, nothing hit the town though,)

At my school they always had a tornado drill once a month or so during the school year.
