I don't think the merges on the east course would incorporate well with a long course from my recollection, east course is where I have the least track time. It is a good educational course.

While I can see the point of face time with turns (# of turns per session), first timers on track really do benefit for the breathing room from one educational experience (turn or set of turns) to another educational experience - ie the straights.

BTW there is no reason not to add another PDX day at a different time on the east course when the north and south courses are in use by other groups. I wouldn't mind more time on it, but most of the time the east course is being used by motorcycles and I am with a group on the south course and one of the arrive and drive schools is using the north course.

Its all good, pot stirred.
