Take the kids to a rock concert this summer. Check out Ralph's World (pictured) at Ravinia on July 12 (reserved seats $15, lawn $5). Roll there by train to make the day really rock! The Metra stops right at Ravinia, so it super easy on little legs.
Or nab tickets to Maroon 5 with Kelly Clarkson (Aug. 25) at First Midwest Bank Amphitheater in Tinley Park.
