"San Francisco's Annual Tricycle Race Draws Hundreds"

San Franciscans of all ages gathered for the annual Bring Your Own Big Wheel tricycle race down the curviest street in the city's Potrero Hill neighborhood, a tradition spanning over 20 years. Participants, including families and kids, raced down Vermont Street, embracing the chaos and fun of the event, which was originally conceived by a man who stumbled upon a big wheel and decided to ride it down Lombard Street. Despite the apparent risk, participants and spectators continue to enjoy the unique and kid-friendly cultural event.
