To help racers and fans keep track of sportsman racing results in the NHRA Lucas Oil Series from NHRA national events, an audio-only version of NHRA All Access has been launched today at the K&N Filters Route 66 NHRA Nationals at Route 66 Raceway near Chicago.  The audio-only version of NHRA All Access will be available on race days when video is not available, which is typically all race days before Friday of a race weekend. Audio-only days are free to the public, but requires a simple registration process. To access NHRA All Access, click here: http://www.nhraallaccess.com/
