USDA zone maps
Some of us-not me-live in zones rated similarly to places way to the south of us.
Sometimes/most cases-this is because of proximity to water.
For instance NYC or even certain areas in Michigan,etc-
may be rated(USDA Zone maps)similarly to southern Mo/North Carolina.
So technically you could live in a place that is rated to
be a warmer zone then a lower rated zone that actually
has warmer avg temps!
The question is-???Would you trade away some of your milder
winter lows in a place like Detroit/Attleboro-for example-
(I realize these climates are not exactly similar) for a quicker
warmup in spring or just plain old warmer spring/summer/fall weather???.
