WHAT IT IS: Nike+ FuelBand is bringing New York some wicked twists on games from your misbegotten youth, from stickball to kick the can. They’ll be putting together massive rosters of eager participants all Summer long, so get ready to play dodgeball in the Barclays Center, and be introduced to the life-changing pastime that is “powderball”. WHAT YOU NEED FOR ACCESS: A Nike+ FuelBand, of course. WHERE: Check out their Twitter for more info. WHEN: Whenever the urge to play consumes them (read: follow their Twitter) WHY: Just because you’re old enough to worry about 401(k)s doesn’t mean you’re too old to care about playing kickball with, like, 401 people.
