@redneck roy Yes! I'm from Omaha. We did them all the time.
Google Omaha tornado May 1975. It destroyed my elementary school. We had to finish out the school year at a neighboring school, by spliting the days with them. They sent us home from school early but didn't tell us why. I was in 1st grade. I went home with my best friend because my parents were out of town. I still remember the sound of it going over the house. It hit 4 blocks from my house. Leveling blocks of houses. It hit the hospital I was born in. Cars were stacked on each other, like matchbox cars. I still remember the sirens.
Does that explain, now, why I tend to notice dark clouds, especially in the afternoon??
