Each year teams of high school students test their solar powered cars with either a closed track event or a major cross country run. The Dell-Winston School Solar Car Challenge is operated by the Winston School in Dallas, Texas, and track events take place at Texas Motor Speedway. The cross country events vary each year and the 2007 route runs from Round Rock, TX, to Newburgh, NY. Day five consisted of a lot of trailering and a short run from a few miles west of Wilmington, OH, to Washington Courthouse, OH. Most of these pictures are from the start point on OH-73 near I-71. The last two are in Washington Courthouse.
