All:
Thought that I was reporting new info - thanks for the clarification and the links Hog.
On another note, there is a colour map/illustration in the AGM Presentation handout that shows the North Corridor. For clarification - it is actually a long Y shape. The corridor actually splits in two and is a long ways (1+km) from the Main Corridor.
I have it scanned but can't post images unless their linked.
