SKY ZONE 459 Orange Point Drive, Suite E, Lewis Center 740-548-4004 columbus.skyzonesports.com You know those jokes about how great the sugar crashes are after your kids spend time at a birthday party? This is better because, after a birthday party at the Sky Zone Indoor Trampoline Park, they are legitimately exhausted, but not in danger of insulin shock. Soon after this Lewis Center (southern Delaware County) business opened in 2010, it bounced (haha) to the top of the ranks of great birthday-party venues. This year, Columbus parents voted it tops.
