S MS tors were in a very rural area. Keep in mind just how tough it is to get EF5 damage in a rural area. EF5 possibilities are in DIs 2 & 5-20. 5-20 are almost entirely found in suburban or urban areas. 2 requires a well constructed home which is also relatively rare in rural MS

Here is a good resource for additional details about EF scale DIs.
