If you're tired of dragging your rolling suitcase around by hand and don't mind looking slightly ridiculous, a new doohickey called My Hitch is perfect for you.
It's a plastic clip that you attach to the back belt loop of your pants, then attach to your suitcase, so that you can pull it around behind you, leaving your hands free while you walk.
My Hitch works best with luggage under 25 pounds, and it can be yours for $17.95. You're advised to wear a belt while using the product lest your pants fall down.
