The Last Time You'll Hear 'Reston Real Estate' and 'On Fire' Together for Some Time

The U.S. Geological Survey, the giant government complex in Reston where federal employees either a) look at rocks under microscopes or b) monitor spy satellites that take pictures of your grocery cart on the way out of Fresh World to ensure you didn't buy anything suspicious like falafel, caught on fire early Monday morning, closing the facility for the day.

A free holiday for employees paid for by our tax dollars -- yay! One of our eyewitnesses sent us this harrowing report:

No visible external damage, but apparently enough to warrant it closed for the day.

Which brings to mind a question: How do rocks catch on fire?
