A year ago, a band of high school students set off from Austin, TX to Los Angeles, California, a trek we would replicate ourselves a few scant months later. Only we did it in an overloaded SUV pulling an overloaded trailer, rather than in a featherweight solar-powered car. And we didn't build the Dodge ourselves, either. This year has been a closed-track event, as is every other Dell-Winston Solar Challenge, ending today at the Texas Motor Speedway. Next year, though, they're back to ditching the NASCAR schtick and taking their show back on the road, from Texas to NYC.
