John Yang, a Diamond Bar local messed himslef up yesterday. i heard he did a feeble stall somehow messed up and tried to brace his fall and the scooter somehow hit him in the head. he didnt have a helmet on. he said he never needs one, and he never lands on his head. Well now he did and he has a couple STAPLES in his head. My dad has been telling him for months and he didnt care. His mom wont let him ride anymore so thats it for him. He was getting really good too. He was progressing really fast. So yeah between all the expierience riders have had hitting there heads i think it is necessary for everyone to wear them now. even on the little stuff. He was doing a feeble stall. easiest trick and he had them like nothing. he just slipped or something and BAM in the hospital.
