"Winter" and regional definitions thereof

[dmaze]

When visiting other parts of the United States remember to keep in mind that local weather may be different from what you're used to. For example, even if you've spent 20 years living in California, ordinary November evenings in Chicago do tend to drop significantly below the otherwise frigid temperature of 50 Fahrenheit. Please dress accordingly.

(Maybe my parents are getting scarves for $WINTER_HOLIDAY.)
