Fun by day and by night during one of the best boogies of the year -- Summerfest at Skydive Chicago. If you missed it this year, shame on you. Now you have to live vicariously through this Summerfest skydiving video. Just make sure to join in on the fun next summer. Until then, check out our home-baked edit from last year's 138-way vertical world record at Skydive Chicago. It was epic!
