From the event annoucement on
SEDIV Solo2 Divisional Series: This Championship Event will take place on over 7 acres of smooth concrete just begging to be autocrossed on!! You can expect a 48 to 55 second course with speeds that are comparable to what we saw at Nationals!
Spence Field's an old WWII-era training base. Still used as an airfield, and judging by the charts I looked at, similar in configuration to Buckingham AAF down near Ft Myers -- I'm guessing the course will be on some part of the old ramp and perhaps one of the abandoned runways...plenty of concrete.
I wouldn't expect to see a course map beforehand...not a common practice at large events.
I'm tempted...just have to find out if I'm supposed to be somewhere else that weekend. Of course, it would be the same month as the CFR event at Daytona....
