Since the zip code finder isn't working on the new maps, I opened the link that allows you to look at your state map individually. According to that map, I moved from Zone 7b to Zone 8a.
Color me skeptical. This is saying that winter lows are ON AVERAGE slightly warmer which is why the zoning changed. I respectfully disagree and base my perspective on local data which was gathered for a lawsuit against the local electric company and their smart meter scam. It's actually been colder, not warmer.... So I'm going to stick with my old designation.
