A thunderstorm that blew through the Black Hills Saturday night caused a large tent, with several people inside, to collapse at the Sturgis Motorcycle Rally.
The tent was located on the Buffalo Chip Campground, east of Sturgis.
A pole supporting the tent gave way during the storm.
According to the Black Hills Area Red Cross, nobody was hurt, but about fifty people were displaced.
The Red Cross says they were members of a church group collecting donations during the rally.
They lost many of their possessions in the storm and were re-located to a different building.
The Red Cross will be back at the scene Sunday morning to further assess the damage.
