More changes to '06 NORBA National Series

USA Cycling announced two significant changes to the previously announced 2006 National Mountain Bike Series on Thursday. Organizers of the series have added a seventh event and both the date and the venue of the opening round in Southern California have changed.

Compressing the NORBA season into just four short months, the originally scheduled Frank G. Bonelli Regional Park in San Dimas, Calif. on April 22-23 season opener has been moved to Southridge Park in Fontana, Calif. 50 miles east of Los Angeles and scheduled for May 5-7 .
