An estimated one million people could be in the Black Hills this week for the 75th annual Sturgis Rally, which officially begins today. That would be the largest numbers of people ever recorded for the event. Last year’s event attracted less than half that, with an estimated 442,000 people in Sturgis. SDPB's Kent Osborne is one of the thousands of bikers at the rally and he joined Dakota Midday from downtown Sturgis.
