If you dig down 4 feet or so you are likely to hit water here, which is why there are no basements. No, I wouldn’t recommend trying to out run a tornado. It’s not that they are moving fast, but rather because they can change directions very quickly. The other problem is getting stuck in a traffic jam situation. When there is absolutely no place to go and it is getting close, find the lowest level ground like a drainage ditch. Never get under an overpass either.
Same problem with Michigan. Very swampy conditions. I’ve gone walking in the woods and sunk in to my mid-calf. The mosquito is their state bird.
A sad outcome in western IA a few years back: the people had gotten out of the car and huddling in the drainage ditch. The tornado picked up the car and dropped it on them, and they died. I guess it was their time....
