I live in southern Arizona, just north of Tucson. I drive through Twin Peaks pass (described as a battle site in one of Web's stories) 5 days a week.

I would think SAMAD would need to control the 1-10 as far north as the 1-8 junction near Casa Grande. That would keep its lines of communication with S. California open (keeping it clear of Mexican army units, marauder gangs, and bandidos is another issue). That would, in my mind, give SAMAD a reason to actively oppose any large marauder groups in Phoenix, assuming said groups also had designs on controlling the junction area. I can see such groups running "tolls" and such.

On a related note, with a presence in Tucson, the I-10 east to New Mexico (or El Paso on highway signs- poor New Mexico gets no love) should be within SAMAD's zone of control.
