MLB Fan Cave is part tourist attraction, part performance art, part social media experiment. In Spring 2011, MLB found one Superfan willing to watch every single game of the 2011 season - over 2,400 games - while sitting on full display in a tricked-out storefront in New York City. The cave was fully equipped with food and drink, a barber chair, baseball memorabilia, and a floor-to-ceiling wall of TVs tuned to baseball from the first pitch of the day to the final out of the last west coast game. Players and celebrities regularly stopped by to hang out with him, watch games, make videos, and keep him from getting stir crazy. And during the All-Star break, when there was only one game all weekend, the entire Cave was moved to the outfield at Chase Field in Arizona – complete with an over-sized hot tub - so our Superfan could enjoy a little fresh air. All the while, our Superfan documented his journey online and was available to discuss and debate all things baseball in real time with fans worldwide. The Fan Cave is currently in its second season. If you're in NYC, you can stop by at the corner of 4th & Broadway.
