Ya, I understand areas where they can happen, but are really uncommon to not have a need for storm shelters. Here in MD, we maybe have 2 or 3 total a year, and they're usually very small. I've lived here my whole life, and I've only once seen a wall cloud, and that was from a good distance. However, I just can't understand why you wouldn't have the in a state like OK, or KS.
Well, we do have one in our KS house, but it was built in..... 1920, I think. It really creeps me out, and it doesn't look like it could withstand much.
