Up to 250,000 bikers are heading into rural South Dakota for one of the world’s biggest motorcycle rallies, a 80-year tradition. The mayor of Sturgis, the city of the start, said he couldn’t stop people for coming and instead encouraged personal responsibility and promised officials would be giving out masks. A city survey found that more than 60 per cent of Sturgis residents wanted the event postponed because the pandemy. The rally could become the largest gathering since the pandemic began. Typically, the event draws 500,000 people to the area. However the bikers will not be allowed through Cheyenne River Sioux checkpoints as part of larger Covid-19 prevention policy, a spokesman for the Native American group said on Saturday. A number of bikers had tried to enter but had been turned back. Under Cheyenne River tribal guidelines non-residents driving non-commercial out-of-state vehicles are never allowed through the reservation. Some of the crowd at Sturgis is composed of retirees and people in the age range deemed most at risk to suffer complications from the virus. Some locals locals planned to stay home. The Sturgis Motorcycle Rally was begun in 1938 by a group of Indian Motorcycle riders and was originally held for stunts and races. The event generates around $800 million in revenue.
