Hillside Terrace is one of the last remaining populated areas. The rest are either destroyed or overrun. The infection actually started in 1990 but reaches Hillside in 1992. When it started, Hillside was only a minor problem until 1994 when things escalated. One of the only reasons why Hillside hasn't been bombed is because the catacombs under the city where used as scientific labs and contain research as to a cure for the infection but it is only brief.
In the build, there is actually a catacomb and you can get into it.
Problem is, it is flooded with infected.
I'd tell you where it is and get some pictures, but I don't want to spoil it.

I am beginning a new side project that may, later on, be used in the role play. It is called "Airborne in the **Bluzone". Much like a generic zombie shooter, you are placed into a city and must kill everything that moves. Catch is; you parachute in. Its basically a small town with a few buildings. You jump in from a plane really high up at regular intervals. I'm pondering whether players should be allowed to be infected or not. Airborne in the **Bluzone will not be a role play, either. Just a survival shooter.
And, seriously, there is an actual catacomb under the city.
