Venue/Date Change Info

We received official word on September 10th that unfortunately, Prairie City Kart Track would not be able to host any events in October.  We are hopeful that they can resume full operations ASAP and we look forward to working with them in the near future.  As such a new venue needed to be secured and Santa Maria Karting Association was able to quickly confirm they could accommodate us.  Due to some regulatory paperwork that needed to be submitted to the county, we had to push the date back a couple of weeks.  This also allows us some time to re-staff the event, but also allows you ample time to secure accommodations and otherwise make plans around these changes.
