Then I realize NCR have no supply line to speak of before the Battle of Hoover Dam.
Old Road via Goodspring lead to Radscorpion and Cazadors, before heading straight to Fiend Territory (assume the Khans isn't a problem).
I-15 still infested by DeathClaws.
More Radscorpion at Scorpion Gulch, if the prison is taken back.
More DeathClaws at Primm Pass.
Nipton was never recover after the Legion's raid.
