Sac-Town is a settlement in northern NCR. The main office of the Happy Trails Caravan Company is located there. The town is also part of the Short Loop.
Sacramento, the former capital of California, is now a lawless, uncontrolled city. In the region northeast of Sacramento, a gang called the 80s can often be found.
Sac-town is only mentioned in the Fallout: New Vegas add-on Honest Hearts, but was going to appear in J.E. Sawyer's Fallout Role-Playing Game called by its full name Sacramento.
