Washington ( CNN ) -- More than 2 feet of snow piled up at the nation 's capital as a blizzard pounded mid-Atlantic states Saturday , cutting power to hundreds of thousands in the region in what the president referred to as `` Snowmaggedon .

In Washington 's Dupont Circle , about 1,000 people packed , rounded and flung snowballs in between outbursts of laughter .

Faced with the swirling flakes , Obama ditched `` the Beast '' -- his souped-up Cadillac limousine -- for an armored , four-wheel drive Chevy Suburban capable of trudging through the several inches of snow . Despite plowing and shoveling , the continuous snow made for a slippery White House driveway . Before the 15-vehicle presidential motorcade pulled out of the driveway headed to the Capital Hilton for Obama 's speech to Democrats , one of the emergency vehicles lost traction and slid into an SUV . No one was in the car at the time . Sliding vehicles in Virginia hit six state police troopers ; three of the troopers suffered minor injuries , police spokeswoman Corinne Geller said .
