Justin Walker has a knack for wrecking cars ... in style. Just 20 years old, Walker, who won the Colorado State Fair Demolition Derby a year ago, walked away with three golden trophies in two weeks. Walker won the Lincoln County Fair Demolition Derby truck division Aug. 12 in Hugo and paired up with his father, Greg, to claim the bus division at the same derby. On Aug. 19, Walker competed in the car division at the Arkansas Valley Fair in Rocky Ford, again winning first place.
