Kids' admission wristbands

Many amusement parks and such issue adhesive wristbands that you (and your kids) must wear to prove that you paid admission (or, in some cases, to show a child's size). Trouble is, kids pick at them and in an hour or two they are torn off. At one of the parks this summer, a stranger shared this tip with me: Put the bands on the kids' ankles instead of their wrists.
