Celebrate NYC's southernmost borough with a full day of family activities, starting with the 1.5-mile Fun Run ($10) at 10:30am—that is, unless your little one is old enough for the Staten Island Half Marathon, which starts at 8:30am ($45-$65). Enjoy carnival games, live music, bouncy slides, obstacle courses and local foodie vendors who've been impacted by Hurricane Sandy. Proceeds from the fest will go towards relief efforts. All ages.
