TOD:
The worst I ever experienced was in Lawrence, Indiana (a suburb of Indianapolis) circa 1981.
It was summertime. My parents were to visit, and I had cut my grass in sunny weather. After I had showered and dressed, I noticed it was getting overcast. It got darker and darker.
My parents arrived from South Carolina, and my mom was very scared because the sky looked green.
We had a hellacious storm, and we all huddled in the bathroom.
Once it passed, we watched the news and learned a tornado had passed just a couple of streets over from where I lived. A lot of damage was done, but we were just fine.
