Don't forget PCQ
And there is also the Pacific Crest Quest - San Diego to Mazama WA.
This summer I built a west to east connector to tie together the northern ends of the PCQ and CDR.... I call it the 'Northern Route'.... it will eventually tie back into the eastern end of the TAT.
It's all mapped, but only the PCQ to CDR section has been ridden.
I provided the western section to Countdown to post on GPSexchange, but don't know if he's done so.
