Arnold is a village in Custer County. The population was 597 at the 2010 census. The village was named for George Arnold, a pioneer settler.
The first Sandhills Open Road Challenge was held in Arnold, Nebraska, in August 2001. Thirty-four enthusiastic drivers came from 17 states to participate in the first event of its kind ever held in Nebraska. The event now sells out its grid of 120 each year on the first day of registration with scores eagerly anticipating being selected from the events waiting list.
Thousands of spectators from Custer County and surrounding communities throng to Arnold each year to watch the shootout, parade, road race, and the crowd favorite–the burnout contest. Drivers from more than 40 states and Canada enjoy unrivaled hospitality from local inhabitants who open their homes to lodge upwards of half of all drivers and navigators. As one driver proclaimed loudly at the 2008 SORC barbeque, “Nobody does it like Arnold!”
