Tonight is when we fall back: the last day of daylight savings. We’ll be turning back the clocks at 2 am. That means the bars are open an extra hour (but the Metro is not) and you get an extra hour of sleep. The downside is, of course, that it will start getting dark around 5 or 5:30. But, for those who wake up early: it probably won’t be dark anymore. Enjoy your extra hour of carousing and sleep: you deserve it after last weekend! And P.S., DC Fire & EMS would like to remind you that with every clock shift, change the battery in your smoke detectors.
