So far, and to my knowledge, for the last 3 years only the Sacramento Chapter of the NSXCA has been hosting track events in Northern California.
This year, we opted to run our events with NCRC and Tracknutz rather than put them ourselves because of our time commitments to NSXPO at Infineon October 8 - 12.
In January, NCRC offered a special packet to NSXCA members for Infineon Raceway by waiving the membership dues requirement. After some marketing and promotion, only 3 NSXs showed up - and the weather was great!
Per my involvement and initiatives with S2KCA, NCRC has also started hosting track events for clubs. So if you want to put a track event without the hassles of organzing it, just contact Troy Allison at NCRC, or Justin Hall who used to own a 98-T black/black.
