Convert your carry-on into a stroller
This had to be invented by a parent who got tired of dragging bags and suitcases around an airport while trying to keep track of your child. The Ride-On Carry-On attaches to a standard wheeled carry-on back to provide your child a seat as you wander with the zombies through the airport. It also has a pull-down snack tray.
