SeriousFun Messtival

Head to the first-ever SeriousFun Messtival for all manner of sloppy fun, including paint archery, a dunk tank, a Pie Face tournament and a human tie-dye machine. Put on by the Paul Newman–founded SeriousFun Children's Network, the fest (messt?) benefits kids with serious illnesses, so go ahead and make a big ol' mess; it's for a good cause. Visit seriousfunmesstival.com to see all of the day's activities and register for the event. All ages.
