Hey Don, glad to hear your coming to the race! I'll be real surprised if I don't see you in the expert A-main.
The track will be blue groove (DRY) for the Nitrocross, so your best bet as a warm up race will be our RC Pro West race on Oct. 6-7. This will be the only other event to be run on blue groove this year. I imagine this will end up being the Nitrocross warm-up race for most people.
