Of course, even if some of those numbers are not right, one has to question the planting of tender plants in a place that can get below 20.
Like SE Louisiana (lowest temp I know of in Mandeville is 7 back in 1989 - it was 11 in New Orleans). Very little survived that freeze.
I'm still not sure if where I am is 8B or 9.

You can't be zone 9 if there's been a low of 7*F. That would put you at zone 7b.
