I moved from 5b to 6a, but I'm right at the edge of it along the southern tip of Lake Michigan. I don't think I'm going to fully embrace that change, not just yet anyway. Our weather is just too unpredictable.
Edit:
@dave might want to update the Zone Lookup area of the website to include the new map. I like how it lists what zone you're in/were per USDA map year.
