Sac-Town is a settlement in northern NCR. The main office of the Happy Trails Caravan Company is located here.
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.
