I saw the sign

Another sign you've lived in San Francisco for a long time:

It hits 73 degrees outside, and despite wearing shorts and leaving both your ever-present light sweater and your jacket at your desk when you step out for lunch, you still walk on the shady side of the street, eat under a tree, and go back inside early because it's just too hot out.

This may also be a sign that I'm going to have to move to Alaska in the globally-warmed inconvenient future.
