Man that is awful I could just imagine grandparents must feel.I bought my son his first Four wheeler when he was 12 him an his buddy ran it through a bob wire fence almost ripped his arm plum off.Luckely everything turn out fine but he was in the hospital for a week.Four wheelers can be dangerous!
Yes, that is sad. My heart goes out to that family. And you're right they can be dangerous. About 25 years ago, my husband flipped his and it crushed his whole face. Thanks to plastic surgery, you can't tell but he is lucky to be alive and refuses to buy one for our son.
