Thousands of action sports fans descended upon Grant Park this weekend for the NBC Sports Mountain Dew Tour. Fans were able to enjoy a host of free activities and see their favorite athletes compete in skateboarding and BMX competitions. However the real star of the event was the newly opened Grant Park Skate Plaza, a project led by the Grant Park Conservancy. Spectators, riders and a national audience via NBC broadcast were able to take a close look at Chicago's newest skate park at its first major event. It was truly a fantastic weekend.
