School's out for summer! Kids have been cooped up in classrooms since September so the last thing they need is oodles of screen time or to become couch potatoes. Whether you buy season passes to your local amusement park or set up a world of fun in your own backyard, spend the warm months outside. Fresh air is something every child needs and it's free! These must haves will help you and your family liven up the great outdoors.
