Yesterday in San Francisco, the "Gran Turismo" racing game franchise held an all-day scavenger hunt in which 12 teams of two participated, ending in an all-out party where the winning team was announced. Dedicated gamers ran around the city, searching for Lamborghinis, Ferraris, Audis and Teslas at historic locations like the Golden Gate Bridge and the Painted Ladies Houses. The mini-"Amazing Race" event launched the "Gran Turismo 5" game.
