Spain kicked off it’s annual Running of the Bulls festival in Pamplona this weekend.
Thousands of thrill-seekers try to outrun six bulls through the city’s streets, over a half-mile course.
Runners are known to get trampled on their way to the bull ring, dozens are injured every year.
Some say the nine-day festival is popular because Ernest Hemingway glorified it in his novel “The Sun also Rises”.
Hemingway was born in Oak Park.
