A.Afew children still use traditional wooden sleds.
B.Veryfew children wear any kind of protective gear, such as helmets, while sledding.
C.Plastic sleds can be used in a much wider variety ofsnow conditions than wooden sleds can.
D.Mostsledding injuries occur when a sled collides with a tree, a rock, or, anothersled.
E.Becausethe traditional wooden sled can carry more than one rider, an accidentinvolving a wooden sled can result in several children being injured. |
