Is the north or the south track shorter? Whichever one is shorter is the one I like a lot. I raced it last year at a CCS round. There wasn't enough room for powerful liter bikes to get away so it seemd like a good track to use your skills to fight for position. It was also one of those tracks you have to think to go fast, which is an Alan Wilson trademark.
I never got back to the round where CCS ran the longer track but I heard the longer one got a bit bumpy from the cars and that some of the barriers were awefully close. Still, a top notch facility and I had a blast there during the Friday trackday/practice day. I can only imagine how much fun a Sportbiketracktime event there would be.
