The following are the provisional dates for the 2011 Oregon RallyCross championship:
The March 20, April 17, May 8, June 12, September 11 and October 9 events will all be at the Washington County Fair Complex in Hillsboro, OR.
The venue for the July 31 event has yet to be determined, but it will NOT be in Hillsboro (that's the County Fair weekend).
I believe the March 20 and October 9 events will be run in conjunction with a Primitive driving school, but I will let Paul chime in for that one.
It has not yet been determined whether or not any of the events will be a National Challenge event.
