They're saying Mount Washington recorded the coldest wind chill in US history, -108°F/-78°C. It didn't hit me till they said "Mount Washington, New Hampshire". It's the same Mount Washington that Lucy, the little black wheelchair dog , summited in 2010! Lucy climbed Mount Washington. Fortunately that was August, not February.
