Bob et. al.,
Sorry for the late reply. PSCC had to cancel a few rallycross events last fall. The September event was canceled due to a schedule conflict that left us missing several key chiefs of specialties. (Remember, we're a volunteer organization!) The December event was canceled at the last minute because a heavy rain a few days before flooded the field that we were supposed to be using.
Our agreement with the farm is that we do not know exactly which field (out of dozens) we will be using until the week before the event. We also have to work around farm activity. They want to put us in a field as far away from neighbors as possible, and it is sometimes a day-by-day decision based on weather and their plowing/planting/harvesting schedule.
Long story short, we use MotorSportReg.com for event registration. The SCCA is sometimes slow in removing canceled events from their own web site, so check with PSCC's web site or MSR for the current schedule.
Hope to see everyone out at the farm for one or more Rallycross events in the coming season.....
