I race at Redding ,its my home track and have been to woodburn many times. Woodburn is faster most of the time.,At redding the air is 2500 and much higher in the summer,I routinely run a tenth quicker at Sac and Sonoma.However, the current owners at Redding are operating the track as well as any and much better then most west coast tracks.The starting line is better and more consistant then above mentioned tracks.
