The Roller Skate Craze 117 years old

More than a dozen shots, some less than a second, of people wearing roller skates in various settings: a young man in skates sits on a low guardrail next to a city sidewalk reading, a woman with a child shoots by, a constable skates gingerly, a man skates by in suit and vest, another cleans front steps, children skate into a room where papa and siblings sit, someone slips at the base of stairs, a man in a cowboy hat moves fast, two jovial chubby women shake hands, our man in the hat trips over a wheelbarrow, then falls again as he rounds a corner, then down goes the constable. It's a crazy day on the city sidewalks.
