Slot car enthusiasts Jack Vance, right, and Bobby "Bobbo" Barley, middle, work on their cars before hitting the track for some more laps Saturday night. Just as in actual auto racing, these 1/24 scale modified and open-wheel modified stock cars can have their handling adjusted using small weights, while different gears can be used to adjust speed and handling characteristics as well. The tool chests they're using are their own, and many racers, especially the veteran enthusiasts, take the maintenance of their cars very seriously with a massive and elaborate collection of tools and materials.
