An individual wearing face covering drags an inner tube type device along the snow, surrounded by other people doing the same thing.  The individual walks towards another individual wearing a red jacket.  The individual hands the rein for the device to the person in the red jacket and sits on the device.  The person in the red jacket pulls the device downhill and the first individual rides down the slope.  The first individual dismounts and resumes pulling the device.  The individual pulls the device along some sort of covered walkway with a moving floor.
