The layout of Sin City is not clear as we have never seen a map, but from details in various stories we gather that Sacred Oaks has: 1) A University (the frat boys from Just Another Saturday Night are from there), 2) An airport distinct from Sin City's main one (Marv tells Nancy to take Wendy to Sacred Oaks and put her on a 'plane) 3) An efficient (possibly private) street-cleaning service (In Family Values, Dwight comments that you never see roadkill out there) 4) A railway station linked to the very old-fashioned-looking Basin City subway system.
