Quick question: Does the Arizona Trail connect the CDT and PCT in the South?

The Arizona trail doesn't touch either of those trails it runs in the same north /south direction.
The Grand Enchantment trail hikes on both the CDT in NM <a ways) and the Arizona trail with other. Trails and cross country in between

No. I would check out the Great Western Traverse/Loop that Skurka came up with linking the CDT and PCT in the south. I'm fairly sure he used some/all of the Grand Enchantment Trail, as Mother Goose stated. I don't know much about the GET though. I know he used some of the AZT through the Grand Canyon too. Between the AZT and PCT not sure what he did.
