I do like the idea of making multiple polls with a "process of elimination" used to come up with the TalkWeather community's ranking of the most tornado prone/unlucky cities and towns. It is something I could do if enough people are willing to participate and the mods are okay with it.
I have no plans to close this thread though. I have already learned a lot myself and would love to keep the discussion going.
Xenia was also hit by: An F3 in 1933 and an F2 in 1989.
Moore was also hit by: An F3 in 1973.
Haysville/McConnel AFB was also hit by: An F3 one month after the initial Andover tornado, and by an EF3 in 2012.
