We been redesignated as Zone 7?

Last frost (Mother’s Day) for the sake of tender seedlings, I’m being conservative with this date. For purchased plants, I will be using the date that I have observed from data gathered from 1990 – 2006. (I can’t remember offhand what that is – I think the first week of May.)
