My poor 6 year old just got her heelies for Christmas (I confess she had to explain to me what they were) and there is no way she can cruise around fast enough to be a threat to anyone. So before we jump all over every child with these crazy contraptions on their feet why don't we try holding the parents accountable for letting their kids run wild all over the hotels and the parks! If it was my kid barrelling full tilt into other people she would definatley not be wearing them anymore in crowded places until she could learn to control herself.
