Every year since 1978, on the first Sunday in December, thousands of motorcyclists ride together in a huge motorcade through the center of the city of Chicago. To participate, each rider must bring at least one new, unwrapped toy to donate to the USMCR Toys For Tots program. Attendance numbers depend on the weather, but upwards of 50,000 riders in past years have made the Chicago parade of bikes the world’s largest.
