LOUDON, N.H. — The forecast calls for rain at New Hampshire, potentially soaking fans for NASCAR's second consecutive Chase race, and putting the threat of a Monday finish in play. Without lights at the 1.058-mile track, the rush could be for jet fuel dryers to wring out the asphalt and make it safe for drivers to complete at least half of Sunday's race before the sun goes down. NASCAR had an idea that would speed up the interminable process.
