Crazy Dash's organizers transform familiar city streets into playgrounds – or digital adventure games, as they put it. Teams sign up and, using their smart phones, follow a predetermined course along avenues and boulevards, taking in key sights from the city as they go. Along the course, they encounter ten or more checkpoints, where they answer challenge questions or snap selfies of a silly task such as singing in the street, sneaking through a fountain's spray, or making eye contact with a stranger.
