We don't close for weather - ever. Because our business relies heavily on our support group for restaurants, entertainment, convenience stores, etc - we all have to work.
On the rare occasion that Atlanta shuts down for snow - they rent blocks of hotel rooms close to the office.
With that said - I did leave work about 1.5 hours early and remote accessed into my computer when I got home - just finished what I wanted to get done for today (I'm covering my position and that of a co-worker fighting lung cancer right now).
