Ken Tubman,
ktubman@shaw.ca, runs the PCA autocrosses,as well I think he is involved with the Calgary Sports Car Club stuff.
The PCA events use one end of the road track with minimal cones so it is pretty high speed, the CSCC use either the road track or the oval, much more a classic autocross with lots of cones.
