So you want to go out and paint the town red, but you have no designated driver. No problem: Just ask your (very) young grandson to drive you around. That's what police say a 54-year-old woman did in Louisiana yesterday. They pulled the 10-year-old driver over after getting a call about an SUV being driven recklessly on a major highway. Inside, they found the boy along with a 15-year-old, grandma Brenda Byrd, and another woman, 48-year-old Sheila Joiner. Byrd and Joiner were arrested; they told officers they had the boy drive because they were drunk. They were booked with contributing to the delinquency of a juvenile and allowing an unlicensed driver to operate a motor vehicle. (More Louisiana stories.)
