Cyclist's Slip Shows Invisible Danger of Black Ice

Can you see the black ice here? Samuel Bearg was cycling in Somerville, Massachusetts when he stumbled upon some black ice and fell, fracturing his knee cap in several places. He said the accident happened as he turned from Broadway St. onto Simpson St. Three women stopped to check if he was okay. As one of them stopped, she slipped too, showing again the invisible danger of black ice. Naturally, he recorded it all on video. Credit: Samuel Bearg
