Oh hey, we were there... the evening apparently 12-15 tornadoes were noted around Nebraska and Iowa. When the sirens went off, we headed to the basement. My hands were definitely shaking. It's been a while since I've been that legitimately afraid.
Getting engaged one night, and two nights later sitting in a basement hoping to be "missed" by a tornado reportedly heading your way - it was a quite the exciting weekend, we had lots of feelings.
