Red Bug Trail (red, from 14 Nov 2011) with yellow Jan 2013 GPS tracks of NTC 1-7, aka proposed New Trail Construction segments 1, 2, 3, 4, 5, 6, and 7. My early favorite, before any ground breaking has occurred: NTC-5.
I do not have a clean measurement of the revised total distance. My guess? Closer to 6M than 5M, as little existing trail is marked to be abandoned. Distances depicted in the GPS links vary from a bit short to waaaay short of reality.
