If you're packing little ones, hit your neighborhood or community parks for fun and exercise that goes beyond the swing-set. Your kids will have a blast scrambling up rope nets and navigating obstacles in fortresslike play ports. See-saws, giant slides, monkey bars, pint-sized zip-lines and mini rock-climbing walls are just some of the wonders you'll find at park playgrounds. And, of course, there will be swings! So pack some sunscreen, snacks and juice boxes and head to the park for some full-body fun. Your kids will be building strength, agility and confidence, and laughing all the way.
